I have a luger with a proof mark that I cannot find anywhere. I think it may be a post war east german mark. It is on a 1914 erfurt. the mark is on the left receiver. it is an "N" on its side over a shield like a tri color helmet decal. inside the shield there is a symbol very much like an infinity sign over which is crossed a pick like symbol. I have looked in constanza's book and in lugers at random. Can anyone help? Sorry, I can't add pictures cuz ain't smart enough to know how to do. Sambo
