This really isn't a reply to anyone specific, but wanted to get in through a crack. Watched the LOTM again for the 2nd time this week, and I don't know if it was discrempancies in filming or what, but sometimes there would be a shoulder strap on Killdeer, and sometimes it wouldn't. Never showed him putting it on or taking it off. My question, instead of having swivels for straps, which I couldn't make out on the movie, could they be using, would it be historically correct, to construct a strap with loops on each end to fit over the butt stock and barrel and be snugged down for transporting? Thinking about doing that for my firearm. It would have to be removable, I'd think the strap looped around the barrel would get in the way of the front sights. Any thoughts? Anyone?
