Flambeau Dial-a-Shell

This device is either a hunting or a target shooting one-round-at-a-time .22 manual dispenser. One puts .22’s in a spring-powered compartment where I have my index finger stuck to resist the spring. Then one puts it on one’s belt and turns the knob which dispenses cartridges like a hotel revolving door. To what time period does it belong? 70’s? Is it still produced?
