This seems to be in good working order and not good visual condition. BUT, it sounds like it could be a bargain for someone looking for a good 4-valve American euphonium. A hard case is shown in the listing. Current bid is $350.
SOLD FOR $600 - GOOD DEAL!

Many photos in the listing, so see those for the cosmetic issues.
