This is a wide open metal Lawton mouthpiece for the tenor sax. This gold plated mouthpiece is stamped a 10*B, and measures a hefty .133”. This is the perfect mouthpiece for the player wanting a huge sound and has the air stream to back it up. It plays with a powerful voice but does take a lot of air! The piece shows minor finish wear for its age but no physical wear, and it does come with a Lawton lig & cap set.
