Neat photo find Dave. Based on the stuff in the background, it looks as though the TK-40 is one of the four that were at the Colonial theater in NYC when the b&w photo was taken December 1953. That arch on the upper right of the picture smells a lot like the arch in the Carmen set that was colorcast October 31, 1953, from the Colonial.

In that period, RCA/NBC had five color cameras it was using to develop color broadcasting. One in a small studio in Camden and four at the Colonial theater.

I could not find a reference number on the TK-40, but if it is camera #4, here is a plot of the spectral response of that camera, taken by the RCA labs on 21 March 1953.
