This is a Yamaha euphonium. It's a type of instrument often used as equipment in brass bands. There are some rust spots and minor scratches, but the tubing itself is generally in good condition. There was no sticking. This instrument was in use until recently. I am not an expert on instruments, so I don't know the details. I will do my best to answer any questions. Shipping costs will be covered by me. *Negotiations are welcome.*
