This is a Yamaha F single horn. I purchased it on a flea market app, but I'm selling it because I no longer have the opportunity to play it. There are scratches and areas where the lacquer has peeled off overall. The rotary valves function normally. There didn't seem to be any problems when I played it. It looks quite used, but I think it's a good instrument for practice. I don't have space to keep it at home, so I would appreciate it if you would purchase it. ⚠️Mouthpiece is not included.
