You are bidding on a vintage Morgan Excaliber tenor saxophone mouthpiece. I bought it new AT LEAST 30 years ago. It has had very little play time, it has sat on my shelf in my practice room for many years and turned an ugly brown, I don't know if the pictures show that. Tip and rails are good. The serial number on the shank is 17634.  Opening is 6E. Again , very little play time. On the top, "Morgan" has been scratched in by hand, I don't know if the picture shows it, but it is there
