CV betekend Common Valve. Is niet voor militaire toepassingen gedacht.
Boven het type nummer staat: QE..... Dat betekent English Electric Valve maar ik leg mijn hand er niet voor in het vuur.

Maar werd dus wel in militaire toepassingen toegepast!

CV(Common Valve)numbers were applied to valves used by the British Services, gradually replacing the Army, Navy and Air Force nomenclature in use at that time. In addition a number of valves used by the GPO were given CV numbers. CV numbers have been around since the early 1940's - CV1 was listed in the "Service List of Valves for Special Purposes" published by the Inter-Service Technical Valve Committee in 1941, though at that time their own Service List of Preferred Valves does not appear to have had any CV valves in. Certainly they were in use in 1942 as the specification sheet for the CV44 is dated 9/4/42, and also the type approval date of CV8 is given as 1942.

Maak van die QE maar 10E/

Overigens het complete 10E/ nummer van de CV1067 is 10E/11448 en dat haal ik niet uit de foto.
