Finished my mouthpiece safari for now (Wick 5BS was the ticket) and passing the remaining contenders on to new homes. All are small shank. Prices include CONUS postage, can send further at cost.

Sorted approximately smaller-larger

Benge 12c: Badly beat up, probably worthless, pay $7 to cover mailing cost or claim it free with anything else.

Bach 11c: Light shank insertion marks, pretty standard small bore piece, good player. SOLD

Mt Vernon Bach 7c: Excellent condition, fantastic high range, great lead piece but I don't play lead SOLD

Bach 6 1/2 AL: Shank insertion marks, you all know what these are like, SOLD

Benge 6 1/2 AL-S: I can't tell this apart from the Bach above, $30

Bach 5GS: Nearly-new shape, nice option for mid-bore tenor, SOLD

Schilke 51D: Nearly-new shape, good for small shank euph or if you want that super deep cup on trombone, $35

Yamaha 52: Noticeably worn but playable, not bad if you want a biggish beater piece for outdoor gigs, $12, or +$5 with any other piece

Wick 4BS: Would you like your Bach 36 to sound like a 42? Buy this $45

I'm interested in the 4bs, can you post some pictures?

Edit: I have sent you a few emails.

Email sent about the MV 7C

Several gone, updated prices on the others.

Oddly have had several people contact about the 4BS and then ghost.
