I have a 1917 Colt New Service that I have a question in regards to the factory vs Army property serial number. The factory serial number is 207856 and the Army number is 98748 (difference of 109108). From what I have seen from my collection and other examples, the majority of the 1917 Colt New Service revolvers have a spread of approx 150,000 digits between the Colt factory serial number and the US Army property serial number. The difference in the serial numbers on the other 4 revolvers in my collection range from 151236 on the low end, to 153555 on the high end. The gun has not been refinished - has sharp edges, markings and the correct grinding patterns on the frame and around the front site, but the area around the Army number has more of a heat treated finish rather than heavy blued. However, it doesn't appear to me that the Army serial number has been ground or altered? Also, the font appears correct with the stylized fonts. I photographed it next to another example to show the similarities and contrasts. Based on the ranges that I have observed, the Army serial number should be around 57000 vs the 98748 which it is. So my question is whether anyone else has seen something like this or have an idea of what went on with this specific example? Could the gun have been held back from receiving the Army serial number for some reason? Any thoughts or input would be appreciated.
