The CV1150 is a directly heated triode on an Inter Services type 1 base. The NR stands for Naval Receiving and as this designation predates the 1941 introduction of the CV or Common Valve specification for UK government valves the valve design also dates from before this period. This exhibit carries the CV1150 designation thus showing that the exhibit was made after 1941.
The wide glass tube envelope is 25 mm in diameter, and excluding the I/S1 base pins is 84 mm tall.
