Thank you for viewing. This is a Yamaha alto horn (tenor horn), model YAH-202. This model is currently discontinued. There are almost no dents, but there is one dent near the bottom of the mouthpiece pipe (see photos 8 and 9). It's not a major dent, so I haven't had it repaired, but it's not in a complex location, so it should be relatively easy to repair. There is no slide sticking or piston cap sticking. A YAMAHA 37C4 mouthpiece is included, so you can start playing immediately after purchase. Also, although it was added later, the rim and cup are gold-plated, which is a nice visual touch. There are stickers on the case, but they are made of a material that can be easily peeled off. If you are concerned, please remove them yourself. The music stand screw is missing (see photo 6). Please order it from a musical instrument store if necessary. Compared to instruments from Asian manufacturers, there is a greater sense of security in terms of build quality and intonation. It's perfect for club activities in junior high and elementary schools, as well as for those who usually play the French horn and want to experience a British-style brass band. - Type: Alto Horn - Color: Clear Lacquer - Accessories: Mouthpiece, with case - Number of valves: 3 valves The product will be shipped in simple packaging, such as wrapped in bubble wrap, so please refrain from purchasing if you are concerned. As this is a used item, returns are not accepted. I will try to offer a discount, so please feel free to ask. Thank you for your consideration.
