This small CRT from GEC has an E for experimental type designation. The face is sensibly flat for 30 mm diameter.

Both anodes are connected together and need 1000 Volts on them. With 1000 Volts on the anodes the Y sensitivity is 0.09 mm/V and the X sensitivity is 0.1 mm/V. The grid voltage of -25 Volts is to achieve cut-off. The screen has a green trace.

The detail picture shows the electron gun and Y deflection plates.

The end window envelope is 37 mm in diameter, and excluding the B9 base pins, is 143 mm tall.
