This Berg Larsen HR offset M. It has a tiny ding in the tip but it does not effect playability, and is in otherwise very good condition. You rarely see them this nice. It has a bullet cut chamber and a classy matching brass cap and ligature. It has a tip opening of 0.096″ Nothing like a Berg for being both warm and projecting. If you’re playing a King, or playing with a band and need to cut through without being shrill, this is the mouthpeice for you.
