Ah yes
They look much like the ones I saw 35 years ago. I love the "plumbing" at either end of the second shot and the RF changover "switch" in the middle.
When I did the E & C I took the TV option in the final year and qualified for my TV ops certificate. That was not part of the course but the two instructors were the examiners for the department and made it obligatory for us to do it.
Those were the days before colour and we used to set up IO camera chains. I got two Marconis from channel 9 when they went to colour and set them up in my garage. They were all valves in those days and needed 2 hrs of TLC for every hour of operation. I had 800 meters of camera cable almost enough to take the cameras down to the park.
I gave them to channel 10 for their museum in 1980.
