Yamaha YEP 211 3 valve euphonium. Easy to play, sounds great. I played this for a couple seasons in the Classic City band. Got serious dents (see photos) which DO NOT affect the sound. Yamaha mouthpiece, and the horn were made in Japan, probably around 1980. New ones run around $2000. (Yikes!). Reduced to $375. Possible swap. Calls , maybe texts are best
