The CV2272 is a small oscilloscope tube with the final anode brought out to a side terminal. The prototype was the VCRX212.
The final anode function is post deflection accelerator that gives a bright trace while maintaining the deflection plate sensitivity of earlier tubes.
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.
