Buescher or Conn Vintage Bass Sax Mpc B59

Nearly impossible to find, here's a real vintage bass sax mouthpiece. This piece is a lot bigger than the other vintage bari pieces I have, so I think that it's a true bass sax piece. This is useful for playing a vintage bass in tune, or for completing your set. There's some scratching on the table, so this piece would be a good candidate to be restored by someone like Brian Powell. If you've never done that before, let me know and I can take care of it for you.
