An old friend who has gone gave his Colt OM .22 to his son a couple of years ago. The son knows that I collect Colts and asked if I wanted to buy it, so I went over to take a look. I'd seen the revolver before but had never inspected it closely. Lockup is as tight as you would want. No end-shake. Finish is very good except for a few scratches, handling marks, and lost blueing around the muzzle. Barrel crown looks excellent.The serial number is 824x, placing it in 1933 if I'm reading Proofhouse.com correctly.Under the topstrap, right where you might expect to see flame cutting, there's a machined indentation at least 1/16" deep. It's shaped like a partial section of a cone with the almost straight edge forward and tapering toward the back as it gets shallower.My first guess is that there was bad flame cutting and someone removed the damaged metal. I know that my 1937 Officers Model 38 does not have any cut like this, and I've never seen one on any other Colt. However, I would like to verify that this is not a normal feature of an Officers Model .22.As a side issue, the sides of the hammer have been jeweled. Am I correct in thinking that this change reduces the gun's collector value?Finally, I am certain that the trigger was "worked on" because my old friend told me so. The trigger pull is clean and a little bit light, but the break is not as crisp as my other old Colts. The double action pull actually is nicer than most Colts I've handled. Still, the known trigger work reduces the value too, right?At this point, I've decided not to make an offer on the pistol. My take is that is would be a fine shooter, but it's not worth the $700+ that I would pay for a nice, untouched Officers Model from 1933. I already have a very clean Officers Model Match from 1960 which is a great shooter.
