YAMAHA47 Trombone/Euphonium Mouthpiece for Tenor Bore. There is clouding and rust on the silver-plated parts due to aging. The shank also appears to have some distortion, likely caused by attaching it to an instrument. While it should be usable for practice, please understand that the condition is not the best before purchasing. The original box is not included. Please ask any questions you may have before purchasing. I can also add more photos if you'd like.
