I have one of the kits Raffles is talking about. It was made by a company called "LS" from Japan. (I'm 99% sure that's the name.)
From what I've read, the LS models were cast from MGC Mausers. MGCs are more rare than Denixes, but they're more true to an actual C96.
I know that Odiwan72 had several MGCs for sale last year. Dunno if he has any left. Might be worth a PM to find out.
