According to this Osprey the guy in the middle is a Japanese Advisor. I think you are right that Copplestone Chinese would be closer. I'm looking at the Officer pack
I think you are probably right mate, the Copplestone Chinese officer is a better match.
I have a load of Tsuba Japanese and they are quite a bit small than Copplestone, mind you, every Japanese person I have ever met is small than other nationalities.
