The 3C22 is a transmitting triode capable of 125W at 1.5GHz.
It was used in the AN/APT-5 radar jamming transmitter. Interestingly this was used as the local oscillator in equipment used to discover the 21cm interstellar hydrogen line in 1951.
The construction is cylindrical with a flat top cathode cylinder and a flat top copper anode placed close to either side of a mesh grid.
