This is the YAMAHA YBB-641II, a classic and highly regarded instrument. I just purchased it used in March. The YBB-641II is known for its clear sound and free-blowing feel. The rod-end bearing action enhances operability, allowing for agile response even in fast passages. There are some minor scratches, but I think it's in pretty good condition for this model. There are two small dents on the main tuning slide, but they don't seem to affect the playing feel or sound. There is no sticking in the rotary valves or the tuning slides. I live in Niigata Prefecture. I can also hand-deliver it directly if you live in a neighboring prefecture. Feel free to comment.
