Restoring a Peterson’s of Dublin System Standard 2 XL315 Bent Calabash

Blog by Steve Laug

The next pipe I have chosen is a Peterson’s System Standard 2 XL315 sandblast bent Calabash. It was one of four pipes that came to me from a friend for work. This one had very loose stem that did not seem to hold on in the shank that he wanted me to have a look at as well as cleaning and freshening it up. The finish is deeply sandblasted and tactile with some grim in the finish and some lava on the rim top. It was stamped on the underside of the shank and read Peterson’s [arched over] of Dublin [over] System Standard followed by a 2 [over] the shape number XL315. It was in great condition when I brought it to the table. There was a heavy cake in the bowl and some lava in the sandblast on the rim top. The nickel ferrule was in good shape but scratches that would need to be polished. It is stamped as well and reads K & P [over] Peterson on the left. The stem was unstamped and was in good condition. There was some light chatter near the button that would polish out. I took photos of the pipe before I started my work. I took photos of the rim top and stem to show the general condition of the pipe. The bowl is heavily caked and the rim top and edges have a thick lava overflow. The stem is lightly oxidized and has tooth marks on the top and underside near the button. I tried to take photos of the underside of the shank to show the stamping but the stamping is quite faint though readable with a lens. It reads as noted above. I also tried to capture the stamping on the ferrule and it is readable but the photo just could not capture it well.    I removed the stem and took a photo of the pipe to have a look at the parts and overall look.I am including the link to the Pipedia’s article on Peterson pipes. It is a great read in terms of the history of the brand (

I turned to “The Peterson Pipe” by Mark Irwin and Gary Malmberg to get some background on the Peterson’s Of Dublin pipes. On page 298 it had the following information.

Dublin 1906-2003 Although Dublin appears under Peterson’s on many pipes over the decades, it has served mostly as part of the brand name. The word first appeared on pipes hallmarked 1906-11 Stamped Peterson’s over Patent over Dublin. The simpler Peterson’s over Dublin first appeared on pipes hallmarked 1912 after the expiration of the patent. Illustrations of pipes in the ’37 catalogue show a random dispersion of the stamp Peterson’s over Of Dublin together with the ordinary Peterson’s over Dublin on every model offered. Specimens of the former will either bear an Irish COM or London Made over England COM and almost certainly date from 1945-62. It was first mentioned in print as part of a model name in ’68 price list, as K&P Dublin, in ’92 for a Danish market line and in 2017.

The stamping of Peterson’s Of Dublin is very broad and cannot really help pin down the date on the pipe. However, XL315 shape came out in 1998 so the pipe is definitely post 1998.

I started my clean up of the pipe by reaming it with a PipNet reamer and cut back the cake back to the bare briar. I cleaned up the walls with a Savinelli Fitsall Pipe Knife. I finished the cleaning of the bowl with a piece of dowel wrapped in 220 grit sandpaper. I smoothed out the bowl walls and checked for cracks and flaws. All looked very good. I cleaned off the build up in the sandblast on the rim top with a brass bristle brush. I was able to leave it absolutely clean.I scrubbed the interior of the bowl, shank and stem with pipe cleaners, cotton swabs and alcohol to remove the tars and oils. It was full of tars and oils that with a bit of work came clean.   I worked some Before & After Restoration Balm into the surface of the briar with my fingertips and a horsehair shoe brush to clean, enliven and protect the briar. I let the balm sit for 15 minutes and then buffed with a cotton cloth to raise the shine. The photos show the bowl at this point in the restoration process.      I polished the nickel ferrule with micromesh sanding pads – using 1500-12000 grit pads. I wiped it down with a jewelers cloth to polish it and remove the oxidation. I sanded the area on the shank end of the stem for the first inch to clean it up and make the taper match the shank taper.

I polished the stem with micromesh sanding pads – wet sanding with 1500-12000 grit sanding pads. I wiped it down after each sanding pad with Obsidian Oil.  I am excited to finish this Peterson’s Of Dublin System Standard 2 XL315 Bent Calabash. I put the pipe back together and buffed it lightly with Blue Diamond on the buffing wheel. I gave the bowl multiple coats of Conservator’s Wax and the stem multiple coats of carnauba wax. I buffed the pipe with a clean buffing pad to deepen the shine. I hand buffed the pipe with a microfiber cloth to further raise the shine. It is fun to see what the polished bowl looks like with deep sandblast all around it. Added to that the polished black vulcanite stem was beautiful. This sandblast System Standard 2 XL315 is great looking and the pipe feels great in my hand. It is light and well balanced. Have a look at it with the photos below. The dimensions are Length: 6 inches, Height: 2 inches, Outside diameter of the bowl: 1 ½ inches, Chamber diameter: ¾ of an inch. The weight of the pipe is 54 grams/1.90 oz. It is a beautiful pipe and the first of the four I am working on for my friend. Once the other three are finished it will be sent back to him. Thanks for walking through the restoration with me as I worked over this pipe. Thanks to each of you who are reading this blog.

      Ah… cleaning out the build up in the tapered shank was the main issue. I cleaned it well. I then polished the end of the stem to take of the build up that was just around where it fit in the shank. After that it was a good fit
