This valve is an experimental version of the VT90 micropup M-OV developed for WWII 50 cm radar.
In the picture the filament connects at the left, the anode is the finned structure in the centre and the grid connects at the right. The construction is coaxial and this valve operated at about 600 MHz with a pulse power output of five kilowatts.
See VT90 for details of the production valve.
The co-axial envelope is 40 mm in diameter and, excluding the base pins, is 95 mm tall.
