This is a Yamaha Cornet YCR-234. It seems to be a long cornet that is no longer sold. I researched this online. Accessories include the case, mouthpiece, cleaning brush, and other items (please check the photos). There are some paint chips and rust. Please check the condition of the exterior in the photos. I received this from my child when they were in a drum and bugle corps, but they hardly used it. It produces sound. (Confirmed) I also tested the operation, and it works normally. There is a dent in the 8th photo, and the part that moves with the dent was a little rusty and didn't move at first, but it started working after applying oil. Regarding other matters, I am not familiar with trumpets, so I apologize that I cannot provide detailed explanations. m(__)m Even so, please consider purchasing with the understanding of no risk and no return.
