I recently purchased a K-22 S&W revolver from a widow of a local gentleman who purchased the gun new when he returned from WWII. While looking the gun over more carefully after returning home I found that the matching numbers on the yoke and cylinder hinge were different from the other matching numbers ( K 1421) which were on the butt, underside of the barrel, on the cylinder, the ejector and on the inside of the right grip as if you were pointing the revolver. What gives with a combination of serial numbers? I had 2 more pictures but I reached the maximum of allowable pictures. You may also acknowledge me through my personal email which is [email protected] Thank you all in advance.
