I think I have only two completely unstamped pipes, and even they have "Italy" stamped on the stem. One I feel sure is a Savenelli, an unfinished billiard; my several other unfinished Sav's have the logo on the shank. I also have what was purchased as an Iwan Ries house pipe, which arrived with no stamp, not Iwan Ries and not the maker. It's a big (Group 6) bent billiard with "Italy" on the stem and no other stamping. It's great for Semois, domestic burley, and long smokes of English blends. For years -- I'm not kidding -- I've been tempted by a small, inexpensive unstamped pipe from a name French pipe maker, but it's lack of stamp puzzles me. It's online so I can't handle it, as I did handle the unfinished (Sav?) billiard. The attraction is a partcularly snappy shape, bowl and stem. I suspect it is some kind of apprentice pipe production done by trainees at the workshop. Otherwise why wouldn't they stamp it? I'm always intrigued by unstamped pipes offered online. Both of mine are serviceable and pleasing pipes, especially the suspected Sav. How about your unstamped pipes? What do you have? How do you feel about it/them? Do you like the mystery or resent the abdication of the pipe makers who send these into the market without identification? Usually unstamped pipes are a whale of a good deal, and that's the main excuse for buying them.
