I have a Giardinelli 25 mouthpiece, and have no idea where I got it or when. It is a lot like my 7B, but quite a bit narrower and about 1/8th inch less deep, while the throat is a bit wider. The cup is funnel like, and the rim is sharp-ish. Just wondering because I can't find it only list of cups I've found.
I'd post a picture but am apparently still too dumb to figure out how to do that.

You probably know that the Bach 25 is a small tuba mouthpiece (30.6 mm internal diameter at the rim, maybe 8.33 mm throat.) If the dimensions match at all, I guess it's a "copy", but of course there's no reason it has to be a faithful copy.
