Interesting. I lived through the era but never knew such a device existed. I do remember the plastic "color converters" you would lay on the screen with green tint on the bottom, clear in the middle and blue on the top. ;-)
Does anyone remember the ads for the "Color V" plastic screens you could put on your black and white set and have instant colour?I haven't seen those ads in better than fifty years.The above system sounds like the one CBS had back in 1950.
Similar, but different. The CBS system broadcast the image in each of three primary colors in sequential fields at a higher frame rate and a lower line count than NTSC. Colors were separated at the camera by a spinning disc in front of the single imaging tube and recreated at the receiver by a larger synchronized disc spinning in front of the CRT. The Col-R-Tel took a conventionally-generated (3 imaging tubes) NTSC color image that contained all the color information in each frame and separated it electronically at the receiver, displaying each color as the appropriate filter passed in front of the black-and-white CRT.

The Col-R-Tel was donated by Dick Carr of Warren, New Jersey. Dave Sica interviewed Dick, and produced this video.
Funny, I can't find a translate to English option !!!
