RCA TK30 ‘Gun site’

This is a screen capture from an introductory article on the RCA TK30 from RCA Broadcast News in 1946. Here we have an explanation of the mysterious gun sight that attached to the top of the viewfinder hood. I think there were two types…this one with a polarized lens and a very simple, slotted metal version that looked like Mickey Mouse ears set very close together.
