This item for sale is a Yamaha full double horn, model YHR-664. As you can see, I considered repairing it before listing, but I thought there might be someone who could use it as is, so I'm offering it for sale now. In the used market, these horns sell for 100,000 to 150,000 yen, but since this one is in a junk condition, I've set the price as above. So, feel free to negotiate the price. Regarding the condition, the slides are not stuck, and the rotors are working. However, the 4th lever might be a bit sluggish. Also, the solder on the 3rd valve slide is detached in two places (see photos 4 and 6). Besides normal use, this model is no longer in production, so it can be used for parts. Those with experience or those learning to repair may also want to try fixing it themselves. Although it's in this condition, there have been many cases of item swapping recently, so basically, no returns or exchanges are accepted. Thank you for looking.
