That would be fun and enlightening, Dave! I was on a flute maker's forum for a few years. Every time I traveled to a distant place, I put out a message saying where I was going. I got invited to visit 7 makers overall - near Washington DC, rural Wisconsin, an island near Seattle, and at a hot spring in Oregon where a man dipped his plastic recorder into the water as he played (try it in your bathtub!).

If we sign our messages with location, it helps us set up visits and could lead to some gatherings.

I guess you could get something for $20. Last time I looked the upline mouthpieces were like $80-$100. But like ligatures, they all play. As long as you get one that allows you to get all the "normal" notes (ie. not double high C....), stick with that. Then get quite good and go through the phase of trying everything under the sun. Then find one you like and stick with it forever (life is too short). I've used 2 mouthpieces since 1975 and they play almost identically.

I know it's an old thread, but I have a 19th c Buffet Crampon on the way to me from Europe that has a bell marked exactly like this (later replacement), so at least a component of another similar one has been found.  Wonder if the OP still has it or found any new info.
