This is a YAMAHA YAH202 alto horn. I am not knowledgeable about musical instruments, so the operation has not been confirmed. Please refrain from purchasing if you are nervous, as this is a used item that has been in someone else's hands. I have included many photos, but please understand that there may be scratches and stains that are not visible in the photos. No claims, no returns, and no refunds. I plan to wrap the dedicated case shown in the photos with packing materials such as bubble wrap and ship it.
