This is a nice hard rubber Hawkins mouthpiece for bass clarinet. These piece were all hadn finished by Richard on Zinner blanks. This particular piece shows some history of past use and some very light oxidation but is otherwise in extremely nice shape. Its outer body, beak and shank are all in great shape. The facing profile of the table, tip and side rails is in very good condition as well.
The tip opening on this piece measures .061”/1.55mm
