I came across a revolver and tried to google some info on the gun. Basically trying to find out if it's a replica and what it's worth. Mark on the side of the gun says XX8 which when I looked it up it said its date was 1872. Not sure if I'm right or not. Only other markings I could find was a tiny picture that looks like two swords crossed. Previous owner told me its not a replica and a few years ago it was worth $600. I don't want to sell it I just want to know if it's authentic. I read that if it has a PR it means it's a replica. I found in two spots it has a small stamp saying PN. My guess is it's a replica but I would like anyone's input.
