I can appreciate all the current interest in the old K-22, I recently managed to grab one to replace one I let go years ago. Serial numbers on this 5-screw model place it in the '48 range, everything is very tight and smooth, the trigger breaks like glass. I have one question about matching serial numbers. Everywhere I look where serial numbers are supposed to match up is correct with exception to the numbers stamped on the crane and receiver portion of the pistol matching the crane. On the receiver portion under the barrel opposing the crane where it flattens out the is a large 4 and small 3, under that is 49434, this number is also stamped on the crane. This number is in the 10K range but about 2K less than the other numbers stamped on the pistol...under barrel, behind the extractor, on the bottom of the grip frame. There are only a few characters stamped on the grip frame, left side has what appears to be a 7, right side has an H at the heel, a 6 at center and another very small stamp I can't make out at forward section. Any help figuring this out woud be appreciated.
