This is a late 70s or early 80s vintage metal Otto Link Super Tone Master mouthpiece for the tenor sax. This piece has been custom refaced by Theo Wanne. Originally stamped a 9, it was faced down and now measures closer to a 7* at .105”. The work on the tip, rails, and table is very clean and looks great, except for the finish wear from the work it has a clean, original look to it. The mouthpiece shows light finish wear, but overall is in outstanding condition for its age. A good vintage Link, with a powerful sound.
