Here's a very nice condition MC Gregory “Master Hollywood” series mouthpiece for the alto sax. This piece is stamped a 4A 18M (medium chamber). This is a later series Gregory, with all the characteristics you want in a Master. It plays with the clean West Coast sound that makes these pieces so popular. The facing does appear to be all original with tip measuring .072”. It shows some light surface scratches here and there and some very minor oxidation, but no significant physical wear to speak of. A very nice player.
