You got your answer.
I've got a safari grade Winchester M70 purchased at the commissary on a US army base buy a family friend in germany, 1965. I have the original bill of sale. I have the original box of Peters ammunition that's listed on the bill of sale. It's been shot three times, and I have the original factory verification group, with three bullet holes in the paper.
Think I ought to go out and see how it shoots?
Yeah.
