The CV1101 UK service receiving valve from 1940 is a double diode triode that is identical to the M-OV MHLD6 and VR101. It would have been used in superhet receivers as signal and AGC detector plus first audio stage.
The KB/Z identifies this valve as being made to specification K1001 or K1006, the B denotes qualification by a UK authority and the Z identifies the maker as MO Valve Company, Hammersmith.
The classic envelope is 37 mm in diameter and, excluding the IO base pins, is 96 mm tall.
References: Data-sheet & 1043. Type CV1101 was first introduced in 1940. See also 1940 adverts.
