Summary
High gain pentode originally designed for use in television receivers and adopted for use in radar and other military applications during World War Two (1939-1945). Normally made with a metal bulb but AWV was not equipped for metal valve production so they produced this version with a glass bulb. 6.3 volt indirectly heated cathode.
