I absolutely love this 1940s factory promo film from RCA , describing how they make metal-can octal base vacuum tubes. Check out the all-American family in the living room, huddled around the radio, dad in 3-piece, reading the paper, mom sewing, little Timmy and Janey player checkers on the floor. Gee willikers!
