These are all large shank, polished stainless steel. They are the newer lighter-weight versions and are in perfect condition with no scratches or dings. They are not the discounted "seconds" that they sell. $90 each.

DHWA-S - a few words about this one since it is not on their web site. DHWA-S stands for Danny Helseth Washington Solo. Danny is a former euphonium player in the air force concert band in washington dc and now lives in washington state and performs as a euphonium soloist. This is his signature design. I measure it around 1.04" diameter with a very wide and comfortable rim. It's medium deep and fairly bowl shaped with a smaller throat than many of the other G&W mouthpieces I have. I like it a lot, but it's too big for me! Might appeal to one of you who like larger mouthpieces.
