This exhibit is a Cossor Metal valve but it also says made in USA. On the other side of the envelope it also gives the actual maker as Ken-Rad. Clearly a re-brand for use in Cossor sets.
The 5Z4 was designed to supply equipment of up to 40 Watts total power.
No pretence the Ken-Rad name is proudly presented on the envelope.
The thin metal tube envelope is 25 mm in diameter and excluding the IO base pins, is 67 mm tall.
References: Datasheet, 1040 & 1043. Type 5Z4 was first introduced in 1935.
