I just looked at a Colt 1911 SN 510xxx. Sorry, but I have not pics right now. It appears to be all correct except the grips and magazine. Correct stamps and no rebuild stamps. The finish is about 25%, but still it looks pretty good. The barrel is perfect inside. Anyone care to give an approx value range on this? I am trying to do a deal, but not quite sure on value. Thanks in advance.
