YAMAHA YHR664D Yamaha Double French Horn All slides pull out without issue. Rotary valves function correctly. Bell is detachable, making the case less bulky and easier to store. As shown in the third photo, one of the stopper screws is missing. However, I have attached a similar part. As shown in the fifth and sixth photos, there is a dent in the lower part of the horn, which is typical for horns. The case has some scratches as well. Please consider it as an extra. - Model: French Horn Body - Included: Mouthpiece 30C4, Case I am not a specialist, so I cannot provide detailed information.
