I'm pretty sure that this is the second video camera that I bought. This one's a mains powered industrial studio camera. “Industrial” being a grade of technology between home user, and broadcasting, both in signal and equipment build quality. And “studio” generally refers to indoor use, and in combination with other equipment. Originally it had a dull green/grey paint job, but it was badly worn, so it got resprayed with white car paint.

A few of its features:
-
Rear panel controlled “back focus”, which has a cable drive to move the video camera pick-up tube physically inside the cabinet. This makes it easy to adjust the camera for different lenses.
-
Runs from internal (random) or external sync.
-
A “line view” switch, which allows you to see a signal coming back from a mixer or recorder, or the signal going out from the camera. Though this signal has to be in sync with the camera, because the viewfinder monitor doesn't have separate sync circuitry.
-
Side mounted camera tube beam focus, beam current, and target voltage, controls.
