This is a Yamaha long cornet, model YCR-2311. Overall, it appears to have little damage, but the tuning slide is stuck, so I'm listing it as junk. There's no other sticking, and the lacquer is relatively clean for an old instrument, so it's a good deal for someone who can fix it. The mouthpiece is not included. The case is a Galax Ultra Case (brown). The case seems to have a list price of over 20,000 yen. It's a good case that can fit anything, even rotary or special instruments, but it's a bit worn, so please be aware of that.
