RARE Dukoff tenor saxophone mouthpiece. This is a Miami made killer piece! It is a M9. This is close r to what Brecker played with the rounded over edge baffle. Look at how nice the rails , too, and table where done from the Miami shop. No comparison to the later models! This is a stellar example of the work that was done there. It is a very good price for a piece is this incredible condition. Any questions... 859 992- 4191 please use text. Thanks!
