Well this is an old post, but I'm hoping maybe someone can tell me about a tenor mouthpiece I just acquired.
I'm hoping someone can shed some light on these pieces... where made, by whom, etc. There is like zero info on the web about them.
I just acquired two of them, for tenor, and I find the "Geometric" model very intriguing. It looks to me to be a lot like a Bob Dukoff Hollywood, circa 1949, made of thin-wall rubber, with maybe a bit more rollover baffle and more scoop in the side walls. It is a very interesting player, and is marked "MC"... I wonder what that means... The facing looks pristine and finished very precisely, with fine perfect-looking vertical machining marks.
The other one is white plastic like a Brilhart, labeled "Kell Maxtone". It doesn't look that intriguing... like a Brilhart Tonalin copy perhaps. Straight side walls.
The "Geometric" model is apparently from about 1950, based on this article:
