Many years ago I purchased a new Hy Score Target Pistol in ,22 cal. As I remember it cost $21.95 which was pretty high in the late 1970's/ It is a single shot had had a very nice gloss blue finish. The breach at the rear opened like a camera shutter by turning a wheel and the pellet was inserted into the back end of the barrel and the breach rotated closed. The barrel broke open for a single cocking stroke. It is fairly powerfull and accurate and well designed and made. Anyone ever seen one of these?
