Cooey made the Sure Shot for sears, and Ranger models for Eatons, though it sometimes gets confusing, as they don't say Cooey anywhere on them. But are same as the Cooey model 60 / Repeater equibalents.
In it's current state you could probably get $75 / $100 if you're lucky. With some cleaning and a good goin' over maybe more. Will shoot any 22LR just fine. As long as it's totally not rusted out. Cycling is sometimes an issue. Bolt has a spring-steel extractor that gets bent/ gummed up and affects feeding, likes to be clean and very lightly lubed for best performance.
All said , if you want to sell it let me know..
