Significant lacquer wear and rust. There's a dent in the mouthpipe. Surprisingly, the bell isn't very dented. The tuning slide is stuck. No other parts are stuck. The pistons move smoothly. A YAMAHA 11C4 mouthpiece is included. The case is more compact than a trumpet's, so I used it for practice. Yamaha no longer produces long cornets, so how about trying one out to experience what a long cornet is like?
