This is a great vintage Otto Link Tone Master mouthpiece for the tenor sax, serial number 1E4. This piece dates back to the New York vintage and is table stamped an 8. It has been cleaned up and the tip and rails addressed to make sure everything is even, and it measures .105". A new bite plate was also installed. The piece is in excellent physical condition, normal finish wear for its age but no cracks, nicks, or major scratches. The tip and rails look great.
