Product ID: 7435GregMasterAlto
Here's a nice MC Gregory “Master” model mouthpiece for the alto sax, serial number 7435. This piece is stamped a 5A 16M (small chamber) and measures .070”. The mouthpiece shows a fair number of scrapes and scratches around its body, but all of the important aspects are straight. There are no indentations in the beak, no nicks or chips to the original tip and rails, and the shank's original metal shank band is intact. This piece plays a little bigger than the Model A or B, and has a fast response. Though stamped a 16, it isn't a true small chamber and has some warmth in its tone.
