This a late 70’s early Babbitt Otto Link Super Tone Master tenor sax mouthpiece. The piece has USA on the shank and facing number on the side. The gold plating is in excellent condition.
The mouthpiece was opened up by Jon Van Wie to a 7, measuring 0.102 with facing length of 45. The mouthpiece has a nice roll over baffle which gives this mouthpiece excellent projection and a quick response.
