I have two New York 7s (which are WILDLY different, by the way-- one with the serif font and much "older looking" outer blank and deeper cup with the other, later one looking like a normal Bach), and an early (periods after the N.Y. and Mt.) Mt. Vernon 7c but have never seen a NY 7c. I've also seen a recent catalogue page from the NY era that only lists a 7, 11, 11c, 12c, 15c, and 22c as trombone options (hilariously, the 15c's description reads: "popular with women trombonists", and the 7's reads: "symphony mouthpiece"), but Bach was a custom mouthpiece maker so conceivably NY 7Cs are out there. Anyone got one? How old? Whassit like?
wanna sell it to me?
