I think I posted this back in '09 on the Association side but thought it might be of some interest now. I had acquired a nice box with some paper contents a couple of years prior but, at that time, failed to notice the serial number on the tape. When I did, it made no sense as I was aware of Roy's serial number range documentation of the K-22/40s. This gun was clearly out of that range. I asked Roy if there could have possibly been one of those guns with the number on this box. He checked and the gun which was native to this box was a 4" M&P shipped to the Ohio State Police in 1941. He said it was not unusual during the war for guns to be shipped in whatever was available. Still looking for the gun but it is a long shot.
