I have an old Beretta shotgun that I am trying to find some info on. I was told it was from the 1890's, which I believe is when Beretta first started making double barrel shotguns. The only markings are PIETRO BERETTA GARDONE. The pics aren't great, but here is what I have. It appears to be 12 gauge, side by side, blackpowder, percussion. I am looking for any info and possible value.
