This is a true story. In the 70's a truck driver jumped out of his chip truck and fled the scales. The scale officer came out to investigate and located two firearms in the cab. One, a customized o3a3. There were no serial numbers. The scale officer was also an FFL holder and part time gunsmith. He figured the rifle was worth quite a bit and the owner must have id'ed it somewhere so he began to take the stock off the action. Expecting to find a drivers license number or social security number, initials, or something, he found nothing. Still not ready to give up he took the recoil pad off. Underneath it tucked into a hole in the butt was a rolled up piece of paper. We unrolled it and written was something like, "This rifle was stolen from John Smith, 2231 Riverside Rd, City, State, and phone number". We called John, located in another state. He had filed a stolen report with his local authorities. He got his rifle back. We got the chip truck and never did locate the driver.
