This large WW2 cathode ray tube has a base and neck that are very similar to the VCR138 and VCR97 tubes of the period but a screen that is very much larger. It could have been made as a demonstration device so that several people could see it at one time or it could have been designed for television reception, we just don't know.

The end window envelope is 320 mm in diameter with the neck at 60 mm diameter, and excluding the base pins, is 620 mm long.
