This is a very cool vintage Dukoff Hollywood metal mouthpiece for tenor saxophone. The mouthpiece was more recently worked on by mouthpiece tech Erik Greiffenhagen and now measures .098”. Its outer body is all in raw brass at this point. The piece does still show the lettering above the BD and the print on the shank. Its white bite plate is in decent shape, there is some small indentations from past teeth placement but nothing major. At this point all of the finish is gone and the piece is in raw brass.
This particular Dukoff plays with a crisp sound, clear projection and very direct response to air flow.
