This is a vintage Dukoff Miami Florida Super Power Chamber D5 metal mouthpiece for alto saxophone. The piece is in very nice physical condition showing typical cosmetic wear around the outer body. Its original black bite plate has a few small tooth marks but nothing major. The outer body is in very good condition around the shank and the facing profile.
These pieces are ideal for the players looking for a bright color with a ton of power and projection. They feature a medium smaller inner chamber with a rather high drop back baffle. The tip opening on this mouthpiece is .065”.
