【Yamaha YHR-321 French Horn / With Alexander Mainz 5 Mouthpiece】 While I wouldn't say it's in pristine condition, the rotary valves function without issue. There's no sticking in the tuning slides. You can play it as is, but I recommend having a repair technician perform maintenance on it at least once. This time, I'm including an ALEXANDER MAINZ 5 mouthpiece. Recently, there have been many cases of item swapping, so I generally ask for no returns or exchanges. Thank you for looking. - Brand: Yamaha - Model: YHR-321 - Included Accessories: Mouthpiece #4
