Hi all, I'm currently looking at a Superposed from a dealer who doesn't really specialize in collectors guns and has posted minimal pictures. I'm really looking for a prewar gun and unfortunately don't have the serial number, but as it's a really good deal I'm hoping to strike while the iron is hot so to speak. It does have the FN marking on the lever, which I believe is distinct to prewar guns, but I'm hardly an expert. Can anyone confirm I've got that right? Thanks!
