Update: I found a "real" model number of the camera.
It's called LDH 0400/01 / NC 8925 040 00101
220V AC 50 Hz 8,5W
I find it amazing that google cannot come up with a schematic or user manual, this is from Philips, they were a great brand back in those days.
A funny feature of it - in the back there is a adjuster knob that controls the movement of the whole vidicon assembly up in the front of the camera via a turning rod, quite ingenious.
