I just picked up an older bike at a thrift store. It says its a huffy sportsman (looks like a cruiser) and apears to be somewhat old (It has stickers of approval from the bicycle manufacturing association). I was wondering if anybody knew when these bikes were produced or anything else about them. Also on the right handle it has the letters L N H and it seems that those may refer to different gears (?) but I'm not sure. Any info would be appreciated, thanks!
