I have a Beck 22LR (fires shorts, longs, long rifle ammo) 6 shot revolver that was made in Germany. I bought it around 1967 in California (it is registered to me in California) and am interested in selling it, but I have no idea of the value. It is in excellent condition, no rust, looks new and has a leather holster that is same vintage. I have too many guns and enjoy shooting larger caliber, so this is one of the ones I wish to sell. Any suggestions how to proceed?
