Years ago I lucked out on my .50 '63 Shiloh Infantry Rifle. I was in a gun shop and the proprietor said - "Hey, you're into the old guns, right? Wanna buy one?". I said "Sure, show it to me". He produced the Shiloh and I asked "How much?" Answer $500! I almost broke an arm getting out my wallet.
This was on the QT for a friend and the gun was not taken into inventory back in the era of our now aborted long gun registry in Canada and the owner was damned if he was going to register it. I was asked if I was going to register it and said "Of course .... nudge, nudge, wink, wink."
I got a great deal of pleasure out of shooting that contraband rifle. It made no sense that an original rifle from the era was exempt registration but a modern repro like a Sharps or P-H Enfield required registration.
A pox on ALL anti-gun bureaucracies!
