This is a vintage Selmer Air-Flow Table B* tenor saxophone mouthpiece that is in excellent original condition. This is a very old Selmer piece. It has a large round chamber. The scroll shank has a very unique design that appears to be hand engraved.
The table, rails, tip and biteplate are ALL in remarkably great condition, and the piece has not been worked on. This is a rare Selmer tenor mouthpiece that has a large, woody sound.
