Refurbishing a 1978 Dunhill Root Briar 41041 Bulldog


Blog by Steve Laug

This is another pipe that came to my work table. It is a beautifully shaped Dunhill Bulldog. It is stamped 41041 and Dunhill over Root Briar on the left side of the shank. The right side bears the made in England stamping with the date number that puts it at 1978. The bowl was in excellent shape and had been recently reamed and cleaned. The finished was dull but very clean. There were no issues with the briar. The stem was also in great shape other than being heavily oxidized on the top sides. There was a small tooth mark on the top side of the stem next to the button as well. What made this one interesting to me was the issue that I often see with diamond shank pipes. The sides all looked the same but were not when measured. The top left was slightly bigger than the top right and so forth. It was not an issue as I did not need to replace the stem but it was just an interesting tidbit and one thing I always look for when working on diamond shank pipes. The next series of four photos show how the pipe looked when I brought it to my work table.Dunhill1

Dunhill4 I took two close-up photos of the stem to show the oxidation and the slight tooth mark on the topside near the button. The underside of the stem was not as badly oxidized but had slight oxidation.Dunhill5

Dunhill6 I mixed up a batch of Oxyclean and put the stem in it to soak overnight.Dunhill7

Dunhill8 While the stem soaked I decided to clean out the shank and airway. I used isopropyl alcohol, cotton swabs and pipe cleaners to remove the tars and oils in the shank. I have found that even when I buy a “refurbished” pipe on eBay I do this and am always surprised at the grime and oils that come out of the “clean” shank. I did not want to use the retort on this one as it was not terribly dirty and had been subjected to a pretty good cleaning before it came to me.Dunhill9 In the morning when I took it out of the bath and dried it off much of the surface oxidation was gone and the mix had raised some more oxidation.Dunhill10

Dunhill11 I put a plastic washer on the tenon and put the tenon in the shank so that I could clean up the edges/shoulders of the stem without rounding them. I sanded it with a medium and a fine grit sanding sponge to start with and worked on the oxidation.Dunhill12

Dunhill13

Dunhill14 I wet sanded the stem with 1400-2400 grit micromesh sanding pads. I worked on the scratches as well as the oxidation on the stem.Dunhill15 I “painted” over the surface of the stem with flame from a BIC lighter to burn off some of the surface oxidation and then wiped it down with Obsidian Oil. The photos below show the stem after that process.Dunhill16

Dunhill18

Dunhill19 I went back over the stem with the 1500-2400 grit micromesh sanding pads until the surface was freer of oxidation. I then wet sanded it with 3200-4000 grit pads and the shine began to show up.Dunhill20

Dunhill21 I buffed the stem with red Tripoli and White Diamond before finishing with 6000-12,000 grit micromesh sanding pads. When I finished with the pads I rubbed down the stem with Obsidian Oil and let it soak in.Dunhill22

Dunhill23 Once the oil had soaked into the stem I buffed the bowl and stem with Blue Diamond plastic polish being careful around the stamping on the shank. I gave the bowl and the stem multiple coats of carnauba wax and then buffed it with a clean, soft flannel buffing pad to raise the shine and give it that like new look. The finished pipe can be seen in the photos below. It is ready for the next pipeman to load up his favourite bowl and have a smoke.Dunhill24

A Unique Piece of Pipe History – A Zeus System Filter Pipe


Blog by Steve Laug

The morning of May 9th started as any other one does for me – a coffee and a plan. I got up early and roused the troops. We loaded the car and headed to the US to get to the border crossing before the long lines began. We were at our destination in Bellingham, Washington by a little after 8:00 AM. We had breakfast with the ladies in my family, dropped them off for a few hours of shopping and then did a few errands before heading to the “Junque” shops when they opened at 10:00 AM. I walked through the first shop and found a small no name pipe that was in very rough shape and decided to leave it behind. I went to the second shop and went through all of the cabinets and finally came to the one belonging to a seller that usually had something interesting in her cabinet. That is where I saw the oddly shaped rusticated briar pipe that was stamped ZEUS on the stem. The seller unlocked the cabinet and I took the pipe in hand and examined it. The stem came out easily and I could see the odd spikes at the end of the metal shank. It was an oddity that I had not seen before so I had to have it. I know it sound lame, but this find made my morning. I had found an unknown to me, odd-shaped system pipe and the pipe hunt had been successful.

The pipe is not large. The bowl is about a group 3 size and has a very wide shank. It extends for about an inch before it is joined by a metal oval tube. The tube was in great shape with no scratches and only minimal dents. An oddly shaped stem fit in the end of the metal tube. The stem bore a star with the words ZEUS stamped under it on top of the stem. On the underside it was stamped Made in U.S.A. There is a patent stamp on the short briar shank in a smooth patch on the left side. It reads U.S. Patent over 2,158,897. When I returned home I took it to the work table and took these photos.

The pipe appears to be in great shape. There is minor oxidation on the stem but no tooth marks. The metal tube had sticky glue areas that seemed to come from a label that had been stuck to the metal. I sure wish that they would not use these labels to mark pipes. The briar bowl exterior is very dirty with dust and grime pressed deeply into the rustication. There was a thick build up of tars and oils in the rustication of the rim. There was a crumbling thick cake in the bowl with the cake on the bottom portion of the bowl being much thicker. The airway was dirty as well and I had trouble getting a pipe cleaner through from the stem. It would be interesting to take this old timer apart.Zeus6

Zeus8 I removed the stem from the shank and took the following photo. It was a twin bore stem that moved toward a single airway in the thinner portion. It formed a Y. The twin bores were quite large as can be seen in the photo. It made me wonder what I was dealing with.Zeus10 The metal tube portion of the shank was also removable and only took a little finagling to get it to come free. It was pressed into place and formed a fairly tight seal. Once it was free the end of the briar shank was visible. It had two imposing metal spikes and an airway entering from the bowl in the middle between them.Zeus11

Zeus12

Zeus13 I took another photo of the three parts standing on end. You can see that the metal tube forms a chamber for the smoke and serves as the mortise area for the twin bore stem. The mystery to me at this point was the purpose of the spikes. It seemed likely to me that some sort of filter system was spiked on the points and extended from them into the twin holes in the stem. They would lie parallel to each other in the metal shank and the smoke would swirl around them in the chamber. I began to wonder if I was missing some key parts of this pipe. Were those parts lost somewhere along the way and what must they have looked like? Those were some of the questions that went through my mind at this point.Zeus15 I knew that the patent number on the shank would give me some help with this. I could search the US Patent site and possibly find the drawings and original proposal for the pipe that the inventor submitted for patent. But before I did that I did a quick search on Google for the ZEUS pipe. Of course the PipePhil site came up and there I found the following information. There were two photos of the pipe – one disassembled and one assembled. The stamping was identical to the one I had as was the patent number on both shanks.Zeus4 There was also a short line to the right of the photo that gave me the quick answer to what I had assumed about the pipe. The spikes and the chamber as well as the twin bore had a clear purpose and I was not missing any parts. The ZEUS pipe was designed to hold 2 halves of a cigarette to act as filters. The spike held them in place and the twin cigarettes extended into the mouth piece. The smoke would swirl around them and the tars and moisture would be absorbed in the cigarettes.

There was also a link to MODERN MECHANIX Magazine dated November, 1939 that was an advertisement for the pipe and gave a simple diagram of the interior of the pipe with the cigarettes in place. The advertisement text is interesting in spelling out the pipe designer’s intention for the design of the pipe. It claims that 80% of the nicotine is removed by this new pipe design. The ad says that smoke drawn from the pipe passes through the two cigarettes which act as filters to absorb the nicotine.
I love finding these old inventive pipes that were designed to deliver what at the time was a smoother, cooler, healthier smoke. This was one of the most unique designs that I have seen.Zeus5 From there I turned to the patent number on the side of the shank. I went to the US Patent website and did a numerical search for the patent number. Here is the link to the number search portion of the patent website: http://patft.uspto.gov/netahtml/PTO/srchnum.htm Zeus9 I entered the patent number 2,158,897 and was immediately given a three page scan of the documents on the site for that number. I have included all three pages below. The first page is a series of conceptual drawings of the device. The second and third pages are the details linked to the Figure numbers in the drawings. It was filed May 21, 1937 by a G. Cippico in the category of Smoking Device. G. Cippico is later shown to be Giuseppe Cippico, Inventor from Rome, Italy. The patent was granted on May 16, 1939 almost two years later. These old Patent details are always an interesting read to me. The theory of how the pipe would work is spelled out and the rationale for it being a new and better pipe is detailed.Zeus1

Zeus3 I put this information on two of the pipe forums that I frequent to see if I could garner any further information. I was particularly looking for the US manufacturer of the pipe. On Smokers Forum I received a response from Chris Chopin (flatticus). He included another advertisement from Life Magazine that he found.Zeus16 The advertisement is for a ZEUS Cigarrete holder that claims to absorb over 70% of the nicotine and tars. It also says in small print at the bottom of the ad under the $1 Ladies Zeus with choice of amberlike colored bits that there are also ZEUS pipes. The ad says that ZEUS is made by L. & H. Stern, Inc., 57 Pearl Street, Brooklyn, N.Y. With that it appears that the pipes were made in the US by LH Stern Inc.

Chris also writes; “There are ads from Stern for the Zeus filter in 1938 in Life Magazine (several times that year), Collier’s Illustrated Weekly, and Time. They start in March and April of 1938 with the filter noted as “A New Way to Smoke”. Then nothing for 8 full years. Not a single ad or mention of any kind I can find past December of 1938 except for a mention in the Rocky Mountain Medical Journal that may not be an ad.”

“Then, in 1946, ads show up in Popular Science, Popular Mechanics, The Rotarian, Newsweek, all over the place, advertising that the Zeus Filter Holder is back, now in aluminum. All but one of the 1938 ads say “Also Zeus Pipes” and not a single one of the 1946 ads does.”

“It’s an assumption, of course, but this makes me think that for some reason the Zeus pipes had a very short life, and you may have one of very few they made.”

Thanks for the advertisement and information Chris. Your post gave me some needed information on the brand and confirmed what I had already found from my own digging. It appears I found a bit of a rarity in this old pipe.

Armed with these details and a bit of historical background it was time to clean up the pipe and bring it back to pristine condition.

I took the pipe apart and put the bowl into an alcohol bath to soak and soften the cake before I ream and clean it. I put the stem and barrel in an Oxyclean bath to soak and raise the oxidation and start the sanitizing process.Zeus17

Zeus18 When I took the stummel out of the alcohol bath after it has soaked for three hours I scrubbed it with a soft bristle brass tire brush to clean out the debris from the rustication. I scrubbed the top of the rim to remove the tarry buildup from that surface. I wiped the surface down with isopropyl alcohol on a cotton pad to remove the dust on the finish.Zeus19

Zeus20 I reamed the bowl with a PipNet Reamer using the smallest cutting head. It was still slightly too big to get to the bottom of the bowl. I used a small sharp pen knife to work on the cake on the bowl bottom and sides.Zeus21 I wiped out the bowl with isopropyl alcohol on cotton swabs to remove the carbon that the knife and reamer let behind. The reamed bowl is shown in the photo below.Zeus22 I used the cotton swabs and alcohol to clean out the airway in the shank and to clean up the two points of metal on each side. I scrubbed down the briar surface that the metal tube slid over. I also scrubbed the metal tube out on the inside with alcohol. I used the sharp pen knife to scrape the inside of the tube and then rinsed it with alcohol.Zeus23 I inserted the dental pick in the airway to use as a handle and restained the stummel with a dark brown aniline stain. I flamed it and repeated the process until the coverage was even.Zeus24

Zeus25

Zeus26 I set the bowl aside to dry and worked on the stem. I had dried it off when I removed it and the tube from the Oxyclean bath but still needed to do some work to clean out the airways. I used pipe cleaners, cotton swabs and isopropyl alcohol to clean out the stem airways.Zeus27

Zeus28 I hand buffed the bowl with a shoe brush to smooth out the stain and to raise a shine on the briar.Zeus29

Zeus30

Zeus31

Zeus32 The Oxyclean had removed some of the white in the stamping on both sides of the stem so I cleaned off the surface of the stem and then used a correction pen to reapply the white to the stamping on both sides of the stem.Zeus33

Zeus34 When it was dry I sanded it with a fine grit sanding sponge to remove the excess white material and to polish the stem.Zeus35

Zeus36 With the stamping repaired I worked on the stem with micromesh sanding pads. I wet sanded with 1500-2400 grit pads and dry sanded with 3200-12,000 grit pads. I buffed the stem after the wet sanding with red Tripoli and then rubbed it down with Obsidian Oil before going on to the higher grit pads.Zeus37

Zeus42 When I had finished with the micromesh pads I buffed the stem with Blue Diamond Plastic polish on the buffing wheel and then gave the stem several coats of carnauba wax. I buffed the stem and bowl with a clean flannel buff to give a clean shine and finish the pipe. The completed pipe is shown in the photos below. It turned out really well and it will go in my display cupboard. I think one day I will have to light it up and see how it smokes but to do that I will need to find a couple of cigarettes to use as filters.Zeus43

Zeus46 Thanks for looking at this unusual piece of tobacciana. It will join other odd pipes that I have found over the years that bear witness to the ongoing and ever-present search for the perfect smoke.
