Tenor Sax mouthpiece in white resin, Meyer Style round chamber, soft and round sound
It could be an old mouthpiece in very good condition and rarely played. Externally it resembles a Meyer, and the opening is not engraved. Measured with external equipment, it appears to be about .085 inch (5*Otto link) or a (E) from Selmer. The room is round, it would seem like a medium. It plays comfortably. Without binding and cap, can be purchased separately (combined shipping discount).
