For sale is a Kosikup medium shank mouthpiece, size 1 1/2. The rim diameter is approximately similar to a 3G, and the cup depth is approximately similar to a 5G. It has numerous nicks and scratches, but the plating is still intact and it's still very usable.
I don't know which instrument this is for. I think the rim diameter is a good bit bigger than the standard Kosikup euphonium mouthpiece, but I've never seen one in person and I'm basing that on second-hand accounts. Perhaps this is a mouthpiece for the "large bore" B&H G/D bass trombone? Any experts out there feel free to chime in!
$40 takes it, including US shipping. Please email if you're interested: funkhoss@gmail.com.
SOLD: Kosikup medium shank mouthpiece (G/D bass trombone? Euphonium?)
