Ohhhhh, Lol...
A few years ago, at the old outdoor Fleamarket here...they used to allow people to sell a few guns along with other household items and so on, so it was not unusual to see a few rifles and handguns and shotguns for sale.
Anyway, some guy had cleaned out his grandpa's garage, had all sorts of things, including three or four complete, cosmoline-gooey M2 Receivers with barrels and so on, meaning, just the rear Stock was off...and he had a box of stocks and boxes of other M1 Receivers and parts.
He said he did not know anything about them other than he thought they were WWII, and was just getting rid of stuff in general, all sorts of old Tools and Bench Grinders and whatever else.
A guy ahead of me bought all the M1 and M2 related things for like $150.00
This was 1996 I think.
I was not particularly up on the M1 or M2, but, later learned a little to where I realized that those various ones represented quite a find.
I had no idea the M2 was so valuable!
Eeeeesh!
Wish I'd been quicker off the Dime there on that, but, I did not know enough, and besides, the guy ahead of me was already making his deal.
What would one do if one did find an old M2 Receiver or complete Carbine?
I think one would have to get the BATF&E Matters arranged beforehand, for a 'transfer' to occur, yes?
So, legally, even if I had been first in line and savvy enough, the situation would have presented a Legal problem to buy them?
