Most of us have picked them out of a pipe shop basket or maybe bought them off ebay, pipes of unknown origin. No stamps, or stamps that give little information and that we don't necessarily believe. No-name pipes, some with no nation stamp, and almost never with a shape number, patent, or another clue. Most of my too-many pipes are somewhat known, and have at least some stamping, although I would always like another clue or two. What are your best and worst pipes of unknown origin, where did you get them, and how do you feel about them, how do they smoke, and do you make up notions of their past? My one unstamped pipe is pretty certain to be a Savenelli; I bought it as a basket pipe when they had a distribution hub not far from the regional airport near me. I bought it unfinished, and though it has no stamp, that as how Sav unloaded its seconds at the time. My only other mystery pipes are those from Puerto Rico and Haiti which are handmade souvenirs and probably not smokeable for more than a bowl or two. The unstamped Sav is, well, a Sav second, a few fills, a nice light weight straight taper-stem billiard and smokes like a champ, thirty years and counting.
