BAR, he might have purchased the carbine after he left service. It was stolen from his house while I was in college. They missed the pistol because that was kept up under a swivel chair with skirt upholstery. Lol. The things we recall from our youth. I wasn’t supposed to know it was there, but had discovered it YEARS earlier. I would pull it out sometimes to look at it as a kid, but always respected it, never pointed it at my kid brother and would wrap it neatly in the oiled cloth dad had it in.
I do recall the carbine was still in it’s shipping box, as it was still the days when they would mail a gun directly to the buyer. He may have purchased it in the early 60’s??
