There's a ton of pipes out there that were made especially for shops, sometimes they bore the shop's name, other times they did not. Sometimes they came from good, reputable companies, other times from obscure ones of questionable origin and practice. Smoking the pipe will often let you know if it was from an okay company or not. I have a few no-namer mystery pipes that smoke circles (rings?) around certain pipes with brand names. Luck of the draw (so to speak), if they're cheap, I'll pick up unknown pipes like that and see if they're wonderful "sleepers."
That's a keen panel prince, Walt. Give it a whirl and test its mettle, if you haven't already. You may never know its origin. It'll have to stand on its own merits.
