Restoring a Hard-Smoked Dunhill Shell Briar OX Bulldog and Reworking a Badly Damaged Stem

by Steve Laug

The next pipe on the table came to us from a seller in Cleveland, Ohio, USA on 04/26/2022. It is a Dunhill Shell Briar Bulldog with a saddle stem that has been “ridden hard”. It is in rough shape as can be seen in the photos below. It is stamped on a smooth panel on the underside of the shank. On the heel of the bowl it is stamped with the shape number OX followed by Dunhill [over] Shell Briar [followed by] Made in [over] England⁶ [followed by] Circle 4T. The stamping is faint in spots but still readable. The pipe has a mix of black, cordovan and brown stains on a Shell sandblast finish and some amazing grain that the shape follows well. The finish was dusty and dirty with grime ground into the nooks and crannies of the rugged sandblast. The bowl had a thick cake and there was heavy lava in the sandblasted rim top and edges. The original stem is on the pipe and it is a mess. The button has a crack on the top side and the underside is missing a huge chunk from the button forward about ¾ of an inch or more. Jeff took photos of the pipe to show what it looked like before he started working on it.Jeff took photos of the bowl and rim top to show the thickness of the cake and the lava coat on the rim top. There was some tobacco debris in the bottom of the bowl. The stem photos show the condition of the short taper stem ahead of the button. Jeff took photos of the bowl sides and heel of the bowl to show the deep and rugged sandblast. It is a beautiful looking piece of briar. Jeff a photo of the stamping on part of the shank. He did not capture the shape number or the Dunhill over Shell Briar. It is clear and readable as noted above. One of the first things I like to do is to unpack the stamping and understand each element in it. I turned to Pipephil’s helpful site (http://pipephil.eu/logos/en/dunhill/shell-briar1.html). The stamping is interpreted as follows: The OX is the shape of the pipe which I assume is a Bulldog. The Dunhill Shell Briar is the finish. Following the Made In England⁶ gives the year that the pipe was made. The circle 4 S is the stamp for a Group 4 in a Shell Briar finish.

I turned to Pipedia’s shape charts on Dunhills (https://pipedia.org/wiki/Dunhill_Shape_Chart). I have included the shape charts from the site. The first is the chart as a whole and the second is a larger version of the right column.From the above information I could see that I was working on a Saddle Bulldog shaped pipe. The chart shows that the OX is the stamping for Saddle Bulldog.

From there I wanted to pin down the date stamp ⁶. The pipe has a patent number on it so that will also help with the date of this pipe. I have included the Dunhill Dating Key Part 2 chart below for you to follow (http://www.pipephil.eu/logos/en/dunhill/cledat-en1a.html). The third column shows the date of the pipe. Since it bears the smaller raised suffix ⁶ it took me to the 1950 box. From there the key tells me to add 1950 + 6 dates the pipe to 1956.I wanted to know more about the Shell Briar/Shell finish and when it was introduced by Dunhill and how that fit the Patent stamp on the bowl. I turned to a listing on Pipedia that gave me the information I was looking for (https://pipedia.org/wiki/Dunhill).

Shell

The Shell is a deep, craggy sandblast finish with a black stain, traditionally applied to soft, beautifully grained Algerian briar. While perhaps not the first-ever use of sandblasting on pipes, the technique perfected by Dunhill is considered one of the brand’s most significant contributions to the art of pipe making. The development is documented in English patent No. 119708/17; preliminary work began on October 13, 1917, and the patent was granted a year later, just weeks before the end of the First World War.

The origin of the finish is famously recounted as an “Accidental Discovery” in early Dunhill catalogues. The story tells of Algerian briar blocks being inadvertently left near a furnace, causing the softer wood to shrink and the harder grain to stand out in a textured relief. The reality, as detailed in the patent application, was a deliberate process of steeping the briar in oil for weeks, followed by a heat treatment. Only then was the sandblast applied to cut away the softer wood, resulting in a durable, lightweight, and cool-smoking pipe.

In 1986, Dunhill introduced a premium version of the Shell finish called the ‘Ring Grain’. These pipes feature a particularly deep blast reminiscent of the classic style of the 1930s to mid-1960s, applied to briar with a superior grain pattern. The ‘Ring Grain’ name was later changed to ‘Shilling’ in 1995. Regarded by many enthusiasts as among the finest modern Dunhills, these pipes are produced in limited quantities and are exceptionally rare.^[122]^[123]

Now I knew that I was working on a Dunhill Tanshell OX Bulldog with a Saddle stem that was made in 1956.

I turned to work on the pipe itself. Jeff had carried out his usual thorough cleanup of the pipe. He reamed the bowl with a PipNet reamer and cleaned up the reaming with a Savinelli Fitsall Pipe Knife. He scrubbed the internals of the bowl, shank and stem with alcohol, cotton swabs, shank brushes and pipe cleaners. He scrubbed the externals with undiluted Murphy’s Oil Soap and a tooth brush. He rinsed the bowl off with running water and dried it off with a soft cloth. He soaked the stem in Briarville’s Pipe Stem Deoxidizer and once it had soaked rinsed it off with warm water to remove the residual solution. He dried it off and rubbed it down to remove any oxidation that was still on the stem. The pipe looked very good when I received it. The bowl and rim top were in good condition but needed work on the blast in the top and damage on the inner edge. The saddle stem had a large piece of vulcanite missing on the underside from the button forward. I took a photo of the rim top to show the condition. You can see the clean bowl and damage to the inner edge of the bowl on the front and back side of the bowl. The stem came out looking clean. The issues noted above are visible in the photos below.I took a photo of the underside of the shank to show the stamping. It is clear, though faint toward the stem and readable as noted above. I removed the stem from the shank and took a photo of the pipe parts to show what I was working with. It is a nice looking pipe.I started by working over the damage on inner edge of the rim. I started with a folded piece of 220 grit sandpaper to smooth out the inner edge and give it a slight bevel. It looked significantly better.I rubbed the briar down with Before & After Restoration Balm. I worked it into the briar with my fingertips and a horsehair shoe brush to work it into the nooks and crannies of the sandblast finish. The product works to clean, enliven and preserve the briar. I let it sit for 10 minutes then I buffed it with a cotton cloth to deepen the shine. The briar really comes alive with the balm. I tried filling in the chipped area on the stem surface with Black CA Glue, carefully layering it on the surface. When it dried, it also cracked fell out. I tried another repair with a piece of mesh like Kenneth described in his blog on the stem repair. Once it cured it too cracked along the remaining edges of the stem and fell out. There was nothing I could add to strengthen the repair. With the various avenues of repair unsuccessful I decided to cut off the damaged stem end. I did it with a Dremel and sanding drum and removed all of the damaged area on the stem.

I rebuilt the new button on both sides with the Extra Strength Rubberized/Carbon Black CA glue. I layered it on the stem surface and repeated the process until the stem was workable. I let the repair cure overnight. Once it cured I shaped and flattened it with a small file. I shaped the slot with small files and a small pottery saw. I smoothed out the shape of the newly formed button and slot with 220 grit sandpaper. It looked very good at this point. I sanded the stem and tenon surface with 320-3500 grit 2×2 inch pads. I wiped the stem down with an Obsidian Oil cloth after each sanding pad.I polished the vulcanite with micromesh sanding pads – 1500-12000 grit pads. I wiped it down with Obsidian Oil after each sanding pad. I used Before & After Pipe Polish – both Fine and Extra Fine to further polish the stem. This 1956 Dunhill Shell Briar OX Saddle Stem Bulldog has a beautiful, unique Dunhill Sandblast finish made in 1985. The rich Shell Briar finish that is identified with some great grain around the bowl and shank. It has some great rugged sandblast that Dunhill specialized in making. The polished black vulcanite saddle stem adds to the mix. I put the stem back on the bowl and buffed the pipe with Blue Diamond on the buffing wheel being careful to not buff the stamping. I gave the bowl and the stem multiple coats of carnauba wax on the buffing wheel and followed that by buffing it with a clean buffing pad. I hand buffed the pipe with a microfiber cloth to deepen the shine. The finished Dunhill Shell Briar OX Straight Bulldog is quite nice and feels great in the hand. Give the finished pipe a look in the photos below. The dimensions of the pipe are Length: 5 inches, Height: 1 ¾ inches, Outside diameter of the bowl: 1 ¼ inches, Chamber diameter: ¾ of an inch. The weight of the pipe is 40 grams/1.41 ounces. This one will be staying here as I do some testing on the durability of the repair under normal conditions. Thanks for walking through the restoration with me as I worked over another beautiful pipe Thanks for your time.

Reconstructing a Broken Stem on Dunhill Bruyere # 51671

Blog by Paresh Deshpande

I had just finished the first of the 30 pipes from my Mumbai Bonanza find, a Stefano “EXCLUSIVE”; here is the link to the write up; https://rebornpipes.com/2019/03/11/mumbai-bonanza-stefano-exclusive-restorationa-month-long-project/

How did I land up with this lot makes for an interesting read and one which I have written about in the above restoration. Here are pictures of the pipes that I received in this lot. This lot contains some very nice collectible pipes, a few well known brand pipes and some mediocre pipe brands. Overall, with seven Dunhills, a Preben Holm #1, a couple of Made in England Pete System pipes, Charatan’s and other assorted pipes, I would say that I had hit a huge jack pot!!! Hence, I like to call this find as “Mumbai Bonanza”.

The pipe that I decided to work on is from this find and is marked in a red circle in the picture below. The stummel surface boasts of some beautiful bird’s eye grain on either side of the stummel while densely packed cross grain adorns the front and back of the stummel and also the shank top and bottom surface. It is stamped with “# 51671” towards the bowl and followed by “DUNHILL” over “BRUYERE” on the left side of the shank while the right side bears the COM stamp “MADE IN” over “ENGLAND” followed by underlined numeral “19”. Dunhill White Dot adorns the top of the vulcanite stem. The stampings on either side is deep, crisp and clear. The dating of this pipe is very straight forward and dates to 1979 (1960+19). However, deciphering the shape code, 51671, proved to be a challenge. The first digit 5 identifies this pipe as being Group size 5, second numeral, 1, identifies the style of mouthpiece as being tapered and this is where the ease ends and led to a lot of confusion with the next two digits. Though the shape appears as Zulu, it is not so since the shank is rounded. The profile of the pipe points towards it being a Horn shaped, but the shape code supports neither a Zulu nor a Horn!!! Well, another mystery which is likely to remain unresolved!!

With this information, I proceed ahead with the restoration of this handsome pipe, my first ever DUNHILL!

INITIAL VISUAL INSPECTION
The chamber is clean with a thin layer of cake which indicates that the pipe has been kept clean by its previous Steward. From what I can see, the chamber walls appear to be without any damage. The chamber is odorless. The inner rim edge show minor unevenness which should be easy to address. It is the outer rim edge that shows significant damage on the left side in 7 o’clock and 11 o’clock directions. This must have been caused due to hammering of the edge against a hard surface to remove dottle!! The rim top surface has a number of dents due to the same reason. The mortise is clean and so is the shank airway. The stummel surface is peppered with numerous dents and dings and scratches. Being a Dunhill, any issue of fills is never to be expected and hold true for this pipe too. These dents and ding are probably caused due to uncared for storage by the previous Steward and further contributed to by the trash collector who had sold the pipes to me. The stummel is covered in dirt and grime and is surprisingly slightly stick to the touch. The briar looks lifeless and dull which is nothing serious to address. The vulcanite stem shows significant damage to the button end, in fact, there is no button at all!! The stem end is missing, well, about half an inch of vulcanite. Heavy and slightly deep scratches can be seen extending upwards from the broken button side. The stem surface is very thin at the place where it has been chewed off by the previous owner. I intend to reconstruct/ rebuild this portion of the stem, including the slot, while maintaining the stem and general profile of the pipe. This will require major repairs. The quality of vulcanite is good. In this project, repairs to the damaged outer edge and stem rebuild will be a major challenge, the stem more so, as maintaining the tapered profile of the stem will need to be adhered to for overall appeal of this piece of briar. Having just finished the tedious restoration of the Stefano, I am aware of the challenges this restoration will be presenting enroute.

THE PROCESS
Since the stem has significant damage, and from my experience of stem repairs (Stefano nightmare!) this will be the most time consuming and laborious part of this restoration, I start this project by tackling the stem first. I was faced with two options in my approach to this stem repair; first was to recreate a new button around the broken part and maintain the existing stem profile with a straight slot and the second option was to cut away the damaged button and reconstruct an entirely new button with a straight horizontal slot, sacrificing the overall length of the pipe. I decided to take the former approach. This decision was partly dictated by the fact that I do not have a rotary cutting blade to cut the damaged button end and partly to my innate desire to maintain the originality of the pipe. It’s a Dunhill after all!!

Now that I was clear about the path to be followed, I sand the stem end with a folded piece of 220 grit sand paper to erase the scratches and provide a smooth surface for the intended fill. I cleaned out the internals of the stem with hard bristled and regular pipe cleaners dipped in isopropyl alcohol. Once I was satisfied with the internal cleaning, I wiped the stem surface, particularly the damaged button end, with a cotton pad and alcohol to remove any traces of dirt and grime. To begin the stem repairs, I smeared a folded pipe cleaner with petroleum jelly and inserted it in to the stem airway. I prepared a mix of CA superglue and activated charcoal and generously applied it over and extending beyond the broken surface and set it aside for curing over night. To be honest, I have not researched and measured the exact length that I had to reconstruct, but eyeballed the length using the longer left side of the stem (where a very tiny raised portion of the button is still visible) as a guiding length. Before moving ahead, I would like to mention here that I had applied this mix in layers, over the week, to achieve sufficient thickness which would help during the filing and sanding while shaping the button and achieving the correct stem profile. Once I was satisfied that the fill had cured nicely, I moved ahead and began the process of filing and shaping the button end with a flat head needle file. And then this happened… As you can see in the following pictures, not everything was lost. There remained a portion of the fill which was intact. Not one to give up and having the experience of the Stefano behind me, I persisted with the reconstruction. I made a fresh mix of activated charcoal and CA superglue, this time around increasing the amount of superglue, and reapplied it over the broken button end after inserting a petroleum jelly smeared a folded pipe cleaner. I continued with the layering technique of building up the fill.The next set of pictures show the progress of the stem rebuild using the layering technique. Slowly but surely, I am getting there!Once I had achieved the desired thickness and having let the fill cure for a few days, I proceed with shaping the button using flat head needle files. I am quite pleased with the way things are progressing at this point in restoration. However, fingers remain crossed and mentally remained prepared for disaster to strike anytime. At this stage, I am pretty satisfied with the profile of the stem, the thickness of the button and, in general, the overall progress on the stem rebuild. Also glad that there have been no further setbacks!!!! With this I proceed to shape the horizontal slot for the button. It is a long drawn process and a tedious one at that!! The inside of the slot needed to be smoothed out while maintaining the thickness of the button edge on either side. I build up the insides of the slot by layering it with superglue, letting it cure, sanding and then applying a fresh layer. I must have repeated this process for good about a week plus!!!! The external surface of the slot was also developed the same way and this helped in maintaining the thickness of the button edge.While the stem repair was progressing at its own pace, I moved ahead to deal with the stummel repairs. Given the size of the chamber, I reamed the chamber with size 4 head of a PipNet reamer. The cake was thicker at the bottom and used the size 2 head to remove the cake. I used my fabricated knife and scraped out all the remaining cake. The amount of cake reamed out of the chamber really surprised me as I was expecting minimum cake. I further used one folded piece of 180 grit sand paper to sand out the last traces of remaining cake and expose the walls of the chamber to ascertain that there are no cracks/ heat fissures. I wiped the chamber with a cotton pad dipped in isopropyl alcohol to remove the carbon dust left behind by all the reaming and sanding process. The walls of the chamber were solid with no damage. This was followed by cleaning the mortise by scraping away at the dried gunk with my fabricated spatula and followed it up with further cleaning using cue tips, pipe cleaners and shank brush dipped in isopropyl alcohol. This eliminated all traces of old smells from previous usage. Continuing with the cleaning regime, using a hard bristled tooth brush dipped in undiluted Murphy’s oil soap, I very deliberately scrubbed the surface of the stummel and the rim top. The original reddish dye was also washed away to some extent. The stummel and rim top was dried using paper napkins and soft cotton cloth. I set the stummel aside to dry out naturally. The damages to the outer rim edge, uneven inner rim edge and stummel dents and dings are now clearly visible in the above pictures after the cleaning.

Next, I decided to address the dents and dings on the stummel surface and the damage on the rim outer edge by steaming them out. I heated my fabricated knife over the flame of a candle, placed a wet Turkish hand towel over the damaged areas and steamed out the dents by placing the heated knife over the towel. Though some dents were still observed, these were greatly reduced when compared to before steaming. The steaming method had raised to the surface all the major dents and dings. However, the outer edge of the rim still remained unaffected. The steaming method having failed to address the issue of the damaged outer rim edge, I decided to use a more aggressive method of topping the rim top. Personally, I prefer to avoid topping as I do not appreciate loosing even one mm of briar estate, but in this instance, I was left with no recourse but to top the rim. I topped the rim on a 220 grit sand paper, checking frequently the progress being made. The damage to the outer rim was so extensive that the even after what felt like ages of topping, the damage was still apparent. Finally, I just did not feel like topping any further and hence decided on another course of action. I would rebuild the outer edge with briar dust and superglue. Having decided on this course of action, I lightly top it on 600 grit sand paper to reduce the sanding marks left behind by the 220. The only benefit derived from this topping was that the inner rim is now perfect and I collected some briar dust!

I tried mixing briar dust with superglue, but to no avail. The moment the two came in contact with each other, the mix hardened. So I resorted to the layering method again, first I layered superglue over the damaged surface followed by sprinkling of briar dust and one final layer of superglue. I set the stummel aside to cure. The only problem with this method is the high probability of presence of air pockets.The next evening, the repairs to the edge had completely cured and I move ahead by filing and rough shaping with a flat head needle file. I further fine tune the blending by sanding it down with 220, 320, 600 and 800 grit sand papers. Here is how the repaired area appears at this stage. I am very pleased with the way this repair progressed.Steaming out the dents and dings from the stummel surface had necessitated that the surface of the stummel be evened out by sanding. I sand the entire stummel using 220, 400, 600 and 800 grit sand papers. The little dents and dings that remained on the stummel and outer rim edge were also evened out under this sanding process. This was followed by polishing with micromesh pads. I wet sand the stummel with 1500 to 2400 grit pads and follow it up by dry sanding with 3200 to 12000 grit pads. I wiped the surface with a moist cotton cloth after every wet pad to check the progress. The repaired rim edge now appears shiny and glossy. This has got me a bit worried as it stands out from the rest of the stummel surface. I fervently pray that this is masked after I have stained it. I rub a small quantity of “Before and After Restoration Balm” in to the briar with my finger tips and let it rest for a few minutes. The balm almost immediately works its magic and the briar now has a nice vibrant appearance. I further buff it with a horse hair shoe brush. I had hoped that the balm would work its magic on the filled area and help in blending it a bit, but that did not happen. I had simultaneously been working on the stem reconstruction by building up the slot and button using the layering technique. Though tedious, I have reached a satisfactory stage from where I can fine tune the slot and button edges. What followed were hours of tedious, back breaking and nerve wracking process of sanding and shaping of the slot and the button. Though the slot is not a perfect horizontal straight opening, rather a slight oval, I have managed to match the profile and dimensions of the original stem and the pipe is definitely smokable. Here are pictures of the progress.For a better blending, I further sanded the entire stem with 220 followed by 400, 600 and 800 grit sand paper. This helps to reduce the sanding marks left behind by the more abrasive 220 grit paper. To bring a deep shine to the vulcanite stem, I went through the complete set of micromesh pads, wet sanding with 1500 to 2400 grit pads and dry sanding with 3200 to 12000 grit pads. I wiped the stem with alcohol after each pad and rubbed it down with Extra Virgin Olive oil to rehydrate the vulcanite. The repairs have blended in very well and the stem now looks a shiny black and beautiful. The internals of the stem was cleaned out using alcohol and pipe cleaners. The finished stem is shown below. I kept the stem aside to let the stem absorb the oil and turn my attention towards the stummel. I decided to stain the stummel in cherry red stain which was the original stain true to the Bruyere line of Dunhill pipes. I use the powder variety of stain and mix it with 99% isopropyl alcohol. I heated the stummel surface with a heat gun and applied the stain with a folded pipe cleaner. As I paint the stummel with stain over sections at a time, I burn the dye using a Bic lighter that combusts the alcohol in the aniline dye and sets the dye pigmentation in the wood. After fully saturating the stummel and covering the whole surface, including the rim top, I set the stummel aside to rest for several hours. By next evening, the stain had set nicely. I mount a cotton cloth buffing wheel (because I do not have felt cloth buffing wheels!!) on the Dremel and set the speed at about 40% of full RPM and apply red compound to the stummel. This does help in revealing the grains gradually; however, my fears had come true. The repairs to the outer edge of the rim did not absorb the stain and is encircled in yellow. To finish, I re-attach the stem with the stummel. I mounted a cotton cloth buffing wheel to the Dremel (actually it is not the brand machine, but a local machine which is similar). I set the speed at about half of the full power and applied White Diamond compound to the entire pipe. I wiped/ buffed the pipe with a soft cotton cloth to clear it of any leftover compound dust. I then mounted another cotton cloth wheel on to the polishing machine and applied several coats of carnauba wax. I finished the restoration by giving the entire pipe a rigorous hand buffing using a microfiber cloth to raise the shine further. The completed pipe looks lovely, fresh and vibrant; the photographs in this case, do not do justice to the appearance of this beautiful pipe, my first Dunhill. I cannot thank enough my friends Mr. Dal Stanton, Mr. Sam Vior, Mr. Victor Naddeo and Mr. Steve for helping me to research and complete this mysteriously stamped Dunhill pipe. PS: The readers would have observed the fact that the rim repair could not blend completely in spite of my best of efforts and still I have highlighted the flaw while the general tendency is to hide it. True, there are reasons for me highlighting the flaws; firstly, if I cannot hide it from myself, than why attempt to pretend it’s not there and secondly, the highlighting will encourage you to have a closer look at the flaw and maybe you could have an explanation for it in the first place and share it with me. This will help me in avoiding these mistakes in my future restorations. Third and most important reason is that a newbie somewhere who is not so fortunate like me to have friends and mentor that I have will also benefit from my mistakes.
