Dukoff D7 Tenor Saxophone Mouthpiece. I am including the ligature that was on it. I tried to take a lot of detailed pictures of the mouthpiece. On the barrel is written "Super Power Chamber Dukoff Miami Florida" and of course, the D7. It is in very good condition, although I don't play any instruments, so I have not actually tested it. Due to the vintage nature of this mouthpiece, I am not offering a return policy, so if you are bidding, make sure you have all of your questions answered so you can make an informed bid. I am happy to take measurements, more pictures, or anything else. This is made out of Silverite. The weight is 77 grams. These often go for over $300.00, but I am starting the bidding out low, without any reserve. I listed this originally incorrectly, and I am re-listing it as a Tenor mouthpiece. The overall length of it is: 4.285" and the inner dimension of where the sax body inserts is .662". Thanks for everyone's help in correcting this!
