Some more pix of the tiny beam index color CRT (Hitachi H6289) used in the RCA CKC021 viewfinder.
The actual screen size measures about 1.3" diag. The CRT is about 5.3" long. Two mirrors are contained in the assembly... the first at 45 degrees in front of the tube to direct the image to the viewer, and another above the tube (seen in the top part of the shell) to direct more light to the 2 indexing photocells (seen in the bottom of the case, below the mirror).
I assume that the small metal box behind the mirror contains an amplifier for the photocell signal.

Reason: RCA camera is actually CKC021 not CK021!
