I acquired a '43 Remington Rand several years back thinking it was fairly original. After reading on several forums, I'm not so sure about its 'original' status. It's been through at least two Army depots over its lifetime, Leterkenny (sp?) and Anniston. Have no clue when it was at either one. But bottom line, it's still an "antique" given it's original '43 manufacture.
I received some rifles and a shotgun that had been my grandfather's. They were handed down to me and I intend to hand them down again when I get further along in years. Can certainly find no reason for selling family heirlooms that are meant to stay in the family. But like Rusty said, this is just my $.02 worth on the subject.
