Vintage O'Brien Crystal Bb Clarinet Mouthpiece - Measures .035

Vintage O’Brien crystal mouthpiece for Bb clarinet. This piece is in very nice shape with no cracks or chips around its body. There is one tiny, minuscule nick at the front of the tip rail, which does not dig through the tip and does not seem to affect play in any way. The facing measures on the smaller side at .035” (.889mm). A classic mouthpiece for players and collectors alike.
