With just a good ol' wooden ruler it measures about 3 13/16" tall. The shank is about 1/2" wide (outside diameter), or 13mm at the opening and 1 3/4" long. The outside diameter of the rim is about 1 7/8", the inside is about 1 1/4".
It's probably a copy of something, but what? I'm not a mouthpiece guru, I have my Helleberg and my Helleberg 7B and those work fine for what I play on.
Any guesses? Thanks!
