I'm trying to find some info on a 1911 colt serial number 12536. It's an early model with the diamond cut wood grips. I did have a list of serial numbers that put it at 1913. How can I check to see if the barrel and slide match the receiver? It's been in my family for decades I think it's time to decide whether to shoot it anymore or lock it up. The patent dates on the slide go from 1897 to 1913 Colt manufacturing PTFA or PIFA can't really see the stamping clearly. Any help would be appreciated or point me to a smith in NC that may be able to help.
