This item for sale is a Yamaha full double horn, model YHR-661. The key is B♭ with a thumb valve. This was Yamaha's first professional model and was their top-of-the-line instrument at the time. Regarding its condition, the tuning slides are not stuck, and the rotary valves function without issue. However, there is one spot where the solder has come loose on the 3rd valve slide of the F-side (see photo 2). Also, the brace on the mouthpiece receiver shows some wear. In the used market, these typically sell for around 130,000 to 150,000 yen, but due to the condition described above, I have set the price as listed. It's not in perfect condition, and I apologize for that, but due to the recent increase in fraudulent exchanges, I am generally offering this item on a no-returns-no-cancellations basis. Thank you for your understanding.
