Back when it was easy to ship back and forth across the border, before ITAR raised its ugly head, a customer brought in a Mini-14 with a ruined barrel.
I sent the barreled action to Ruger. In due course, a Mini-14 barreled action arrived back. It had the same serial number as the one that I had sent. It was a new receiver and barrel, not the receiver that I had sent. The bolt and other parts were the originals. I suspect that rather than rebarrel the original receiver, Ruger just installed the action parts on a new barrel/receiver unit and applied the original serial number.
If this revolver could be shipped to Pietta (or the factory authorized service center) for repair perhaps a new receiver and cylinder could be installed and appropriately numbered.
