I'm on Google now, researching some info, but I always like to post here with questions as well, so.... I see people on here posting about C&Rs, which I understand to be curios and relics. But, from a few things I've read, it led me to believe that you have to have some form of license to purchase these. Is that true? What makes a C&R, a C&R? Any must haves? I always see folks on here posting about Mosins. Up until I got on this site, I'd never even heard of a Mosin, and I always thought myself to be fairly well informed on firearms. Atleast compared to most folks. So, OT, talk to me about C&Rs.
