My mom gave me a gun that was my great grandfathers. It is a 1925 Colt 1903 .32 ACP. The gun has the matching serial number 462XXX. Now, this appears to fall in line with the serial number for the Type III buing built in 1925-1926; however, the gun doesn't look like a Type III. It looks like a Type IV. I had a theory that this may have been built at the end of the production life for the Type III and the tooling was changed over and it was produced along side the Type III, but I'm not sure. I've asked some Colt people for some more insight. I may have an odd gun (marked by Colt as a Type III by SN but was one of the first Type IVs). Here is a quick camera pic:
