I am looking for info on a 1911 serial number. It's marked C92XXX. On some sites they claim that puts it in 1918 manufacture, but I know for a fact that the original owner died in France in 1917. I think it's a 1914 manufacture, but the C is throwing me off. I am by no means an expert when it comes to looking up this stuff and am hoping that someone can help me out.
