This is a Florida vintage Otto Link “Slant Sig” hard rubber soprano sax mouthpiece. This is an incredible piece, stamped a 5* and measuring about .064”. This piece is in phenomenal condition, the only noticeable wear is a couple light scratches right on top from a previous ligature. The mouthpiece is completely original and looks great. It shows only light oxidation for its age, and the tip and rails are still in pristine condition.
