This is an older series gold plated Peter Ponzol M2 model mouthpiece for the tenor sax. This piece is stamped a 110 but measures closer to an 8* at .115”. The piece shows mild tarnish and only faint plating wear, mostly on the table. The tip and rails are in pristine shape with no nicks or playing wear to them. The original black bite plate does have a couple teeth indentations as seen in the photos.
