This GE10 has its internal structure obscured by the gettering. What can be seen is a small cylinder near the base and a wire frame higher up in the envelope. These characteristics suggest low power and high voltage. The valve is a diode but we have no details of its design purpose.

The wide glass tube envelope is 27 mm in diameter and, excluding the IO base pins, is 60 mm tall.
