I need to identify this gun and place a value on it. It is a K Frame .22 with 4 inch barrel and adjustable sights. There is no model number under the yoke. The serial number on the bottom of the grip (and on the bottom of the barrel under the yoke is K116XXX. I believe the black plastic grip adapter was standard equipment. There is also a screw in the front of the trigger guard that does not show up in the attached photos. Overall the gun appears to be in excellent condition. I'd say the bluing is 99% +, though it is a dull blue, not the bright polished S & W blue I am used to seeing. Thanks for your help
