I'd be willing to bet that it's on a J Frame. I'd snatch it up in a heartbeat at that price. I bet you could clean it up pretty nice with some 0000 steel wool and oil, then wax. I know some say to NEVER use steel wool, but I've had pretty good results with it making rough old smiths look like pretty slick old smiths with patina. I appreciate the wear they obtain over time....but that's just me.
