That's a pretty good indication that your gun didn't leave the factory as a nickel plated gun
Interesting, could be. Is there any way to tell other than getting a letter? Maybe someone had the hammer and trigger nickeled afterward, otherwise the gun must have been nickeled early in its life because it sure wasn't done recently. The seller said he was selling it for the widow of a deceased friend and that it hadn't been shot in many years. Some of the nickel is flaking off the rear of the cylinder in pieces.
I picked up the SCSW at the library today and it says that square butt models are scarce and worth twice the value, so I guess I did alright.
