Pipe is stamped BBB in a diamond, above "Custom Made", above the ®. Aged Imported Briar on the bottom, and the number 11 on the other side. I can't seem to get a pipe cleaner, or anything else for that matter, more than something like an inch and a quarter into the shank/mortise. The stem appears to screw onto something-like-a reverse stinger...? It cleaned up super well other wise, it'd be a shame if I can't clean out the stem. I've included pictures of the pipe, and my ugly mug, for clarification. Thanks guys. You can mail me any bills from the Optometrist. :lol:
