Really?



Really?


Three approximate dimensions, no mention of cup shape, bore, anything.


And you designed and sell your own mouthpieces.

And you think, after designing your own mouthpieces that "4 inches long, 2 inches wide, and a half inch at the skinny end" can give you enough information to draw a conclusion about what the mouthpiece is like.


Really?

I have a Holton 52 sitting here. Never have found a use for it until now. It is 3 11/16" long.

Edit: Looking at it more closely than I have before, there appears to be a seam at the base of the shank, down in one of the "valleys" that are turned into it. So Maybe the shank is not original?

I have an original Parke Offenloch and a Laskey 30H, both american shank, sitting here. The external dimensions of both are within 1/16" of each other. Pretty sure most all tuba mouthpieces would be described as 4" x2" by a non-musician. I have no personal experience with any of your reference mouthpieces or anything other than your original non-screw rim solo mouthpiece. Sooo... I'm probably not of much use to you.
