Bach Mt. Vernon 3C - 41 backbore

Original condition Mt. Vernon Bach 3C mouthpiece with a 41 backbore and 28 throat. This mouthpiece would have been a custom order from the factory and is in excellent condition for its age. The 41 backbore is one of the tightest backbores Bach offers, and the 28 throat gives this piece some resistance and a lot of "zing". This is an excellent commercial 3C and an incredibly rare piece of Bach history.
