This is a Yamaha euphonium. It's a type of instrument often used as equipment in brass bands. There are some scratches, but the tubing itself is generally in good condition. There was no sticking. Pistons are normal. I am not an expert on musical instruments, so I don't know the details. I will respond to questions as much as possible.
