I had a good chuckle at a lot of the pedantic comments about originality. I’m sure there are a few gray areas, but in general in my experience it’s clear when you handle a gun. This one is a repro from the 50s-80s, this one is more contemporary, this old rusty thing is at least 140 years old, this original Colt 1851 is in nice shape for its years, this poor cut down musket is rough as a cob, this is a gorgeous Pietta 1858 repro, etc etc. I think it’s a very relevant question, too.
I am sure in the ‘50s (when the civil was was “only” 90 years ago) there were a lot more original guns about, prices were accessible if not downright cheap, and most people probably shot the real thing. Then the real things became real collectible, reproductions good and bad began to be made, the muzzleloading hobby gave birth to a lot of skilled builders making them more or less “just like the originals,” and now the default option is to buy a repro according to your tastes and budget, and save the original to admire as a piece of history, but not shoot, at least much, since they’re only “original” once, and using something makes it much more likely to wear out or parts to break in the ordinary course of events.
I own a couple of guns that could be called originals, and I shoot them, but sparingly, like once every few years. I figure if my “collection” is so big I am resolved never to shoot a gun.... it probably means I own too many of them. On the other hand the more recently made guns provide most of the same experience so I’d rather put the scratch, ding, or get caught in a surprise rainstorm with one of them.
