This is an early 20th century vintage hard rubber blank mouthpiece for the tenor sax. This piece has the style of the early teens and 20's, with a large round chamber and little baffle to speak of. The piece is in phenomenal shape for its age, really no noticeable wear, and still has the original metal ring around the shank. There are no teeth marks on the beak and the original tip and rails are perfect. Tip measures .060”.
