New to the forum. Hope I'm in the right place, but here goes. I bought a group of handguns recently, and included was a Smith and Wesson 22LR revolver that I don't recognize. It has 4" barrel, 6 shot, flat latch cylinder release, and the only number I can find is in the yoke, 8850 with a capital H above it. Serial is 574x. Very light, but attracts a magnet. All the standard S&W logo on side and emblems on the wood grips. I'm sure it probably something everyone knows...except me.
