The H&R is a solid revolver, though prone to timing problems and amateur gunsmithing. If fully functional, it is a good plinker. The early ones have some collector interest if in new or near new condition, with value running about $250. The post-war model is common and value is only about $100 even in perfect condition. These are retail prices, of course, not what you could get from a dealer.
The other gun sounds like one of the hundreds of thousands of "Saturday night specials" imported prior to 1968. There are a few exceptions, but most are not high quality (read "junk") with values in the $50 range if that. If the gun functions and is reasonably accurate, it might be a plinker, but don't count on it working for any period of time. It won't "blow up", but it will break or wear after a relatively few shots.
