Product ID: BP3PortnBbJM
This is a nice B Portnoy hard rubber BP3 mouthpiece for clarinet. The mouthpiece is in excellent physical condition. Its body, beak, shank, table, side rails and tip are all in great shape. All of the original vertical facing markings are still fresh looking on the table and side rails.
The tip opening of this piece is .050” or 1.27 mm. It plays with a brighter and more open sound.
