Bloody awsome find mate!!!!
That is a great find, and it working is a bonus!!!! Good one!!!
Closest I found to an old TV over here in Australia when I go junk hunting on the streets is the front face of a late 50s/early 60s B&W set which was probably an early Philips, Astor or AWA brand, I didn't take it as at the time it wasn't on my priority of wants, I was looking for vintage videotapes containing early Aussie shows of the 70s at the time. One of my luckiest finds on the street however was a 1979 PYE VCR1780 (Philips N1702) VCR machine, well actually my mate found it and took it back to his shed and called me up and I have it in my collection, the video heads are stuffed unfortunately but I just keep it as a collectors piece.
Anyways glad you got your CTC-5 displaying a picture and best of luck with the restoration on the set.
