I recently was given a revolver for some assistance I provided. The problem I'm having is actually determining if it is an actual Colt. Took it to the last gun show and was told it was a Colt, unfortunately due to replating the only identification on it is the serial number 63752. This number is on the strap on the grips, the trigger guard and the body, all matching. I was also told that it was originally a 7" barrel but had been cut down to 5 and 1/8. It is single action, nickel plated. When you cock the hammer the cylinder does not rotate back to the left, but, will rotate to the right. There is probably an fraction of an inch play, forward and back in the cylinder. Don't have any idea on the caliber, but was told it is black powder. If I sound ignorant, it is because I've never touched a revolver older than 20 years old. I have a Colt A11911 that was used by the british. My goal is to learn what ever I can about this revolver. Don't have any pictures to provide at the moment.
