This is a metal Florida vintage Otto Link Super Tone Master mouthpiece for the tenor sax. This is one of the earlier “no USA” Florida pieces. It is stamped an 8 and measures true at .110”. The bite plate may have been replaced at some point, it is hard to say for sure, but the rest of the piece does appear to be original, including the facing. The mouthpiece shows mild finish wear as seen in the photos, all purely cosmetic. It is a fantastic player, has a big sound with excellent projection and a quicker response.
