① The Nikkan No. 3 was a professional model at the time, and the serial number suggests it was made in 1963. Considering its age, it's in miraculous condition, with no lacquer peeling. However, there are some surface stains and grime that won't come off with just a regular wipe. ② There's a very slight dent on the crab-claw of the second valve slide, but otherwise, there are no dents at all. It can actually be used for playing, and I think it's also very valuable as a historical artifact.
