My father is a petroleum engineer and recently was working on a rig in south Texas and one of the workers was talking about a gun that he had for sale that he didn't even know what it was. He just said it was "old". Dad is always interested in a new old rifle, and said he was interested. The worker came in with this M1 Carbine, and dad offered the clueless fool $200 for it, and the transaction was quickly made final.
Dad and the rifle:
The receiver is stamped "National Postal Meter" number 4169693.
I read on another site that NPM would use "spare" barrels from other companies and that the bayonet lug was important. Here is a picture of that:
There is a stamp in the stock that looks like RRA-C, but we have no idea what that means.
Clearly this rifle is worth more than $200. Does anyone know what kind of ballpark this would be worth to a collector, or should we just shoot the hell out of it and enjoy it. It is in very good condition, and looks like it has been carried across Europe then put in a closet for 60 years.
Thanks in advance.
