This is disinformation, meant to deflect possible guilt away from LHO, toward a pet conspiracy theory. I have no idea what LHO did or did not do on that fateful day. But others have demonstrated that he could have very well done what he is accused of doing with that rifle. Done deal, kids.
So let's be good freepers and put that part of the story to rest, because it's getting in the way of uncovering the facts.
BTW, don't let the low price fool you. As kids, we all bought surplus military rifles. I (still)have a British .303 "Jungle Carbine" that I bought for $19.95. Mail Order. I still shoot a 6.5X55 Swedish Mauser carbine I bought mail order for $29.95, which was in brand new condition, and I knew a kid who bought the Italian job, which at one point was going for $12.95. Junk. But, he shot a moose dead with it, with one shot.
The paraffin test on Oswald's cheek after he was arrested came out negative.`
