This is a Schott 626. It's a US size S, which I believe is equivalent to a Japanese size M. Length: 65cm Shoulder width: 41.5cm Sleeve length: 64.5cm Width (pit to pit): 48cm Hem width: 48cm Waist width (at the narrowest point): 46.5cm I purchased it new and wore it a few times, but I don't wear it much anymore, so I'm selling it.
