Re: 1937 RCA Projection TV "gun"
Thanks for the link to the Karolus display, most interesting. I had wondered if the lack of flicker that you usually see when a TV appears in shot in a cine film, meant that the picture was produced by special effects. The persistence of filament lamps could account for the the lack of flicker, meaning that it was indeed a straight shot of a Karolus display.
