How about this 22 Cal. Offical Police at a gun shop I frequent. Serial #25756 with a K centered under the SN. Looks to be about 98% with some cylinder ring. A Micro adjustable rear sight in a dovetail slot. Front sight a ramp with what looks like three faint pin marks, maybe holding sight to original sight? Almost new wood checkered grips with silver medalion. Colt Official Police-22 Cal. Cart. stamped on the side of the barrel. I am attracted to old odd pistol configurations. Does not look like a reblue job. Although the barrel might be. Is this a King rework.
