This is a YAMAHA mellophone, model YMP-201. ・Sound confirmed. ・No distortion or dents on the bell. ・No distortion or bending on the mouthpiece pipe. ・Pistons move well, oiled. ・Only the slide in photo 18 is stuck and won't come out. It can be played without issue if you don't need to swap it for the Es main tuning slide. Other slides move in and out smoothly, no problems. Greased. ・Little lacquer peeling, some rust. ・Only one dent. (I looked carefully, but I apologize if I missed any) Please check photo 16. ・Hard case and mouthpiece included. The condition is good for an old instrument.
