A Teaching Moment

This photo was taken between late 1946 and early 1948. How do I know? Because, when the RCA TK30s arrived at NBC New York, they initially put the NBC logo on the viewfinder and the WNBT label on the camera body. When the TK10s arrived a few months later, they decided the red metal strip on the TK10 viewfinder was the perfect place for the call letters, so they flipped the layout.
By early 48, NBC NY had gone back and flipped the art on the TK30s too for continuity. This became the standard for all the O&O cameras. In late 53, the NBC Xylophone logo was adopted and a black and white version was put on the RCA TK10s and 30s, and a color version was placed on all the RCA TK40 and 41 cameras, that until then, had no markings. Now you know.
