This is a very nice, vintage Geo M Bundy mouthpiece for the alto sax. This is a true hard rubber mouthpiece, stamped a 3, and measuring .067”. The piece is completely original, and besides just some minor scratches, really shows no major wear. The tip and rails are in flawless condition. The Bundy name has come to mean student level, but this is a quality vintage piece, and is better than all the student stuff being made today. Plays with a very rich, colorful sound.
