I don't know if these were sort of news reels before movies, or an actual television show, but have the Popular Science films ever been collected and make available for consumers?
Somewhere in my VHS collection I have a tape of vintage Popular Science shorts I bought used from a video store. It's a commercially-produced product, but I can't seem to find any mention of it online.
Though not exactly what you're looking for, you should check out the Prelinger Archives over at internetarchive.org. He had tons of vintage science and education films for free download.
