- Rocky Jones: No hits
- Flash Gordon: Two hits but both from animated shows
- Buck Rogers: Seven hits but from animation and or the 1979 live action show
- Tom Corbett: One hit but not live action but maybe what you want

The fourth release was called Tom Corbett's Adventures in Space and had the following design:
Finally there is the again named Tom Corbett: Space Cadet but with a final design change:
While they all had different packages they all had the same three story reels which you can view at the following links
If this isn't what you are looking for I did find a decent database with no malware (harder than I thought it would be) called The View-Master Database which might be able to help you out.
