This NR52 is metalised with a typical Mullard paint. The NR52 is a British Navy receiving valve, the commercial equivalent is a Mullard 354V triode, a design that dates from 1929 with improvements in 1930 and again in 1935. The μ for this valve was 40.
The NR52 was used after 1941 when CV designations were introduced, the type then was classified as CV1173.
The dome carries the type designation and the Admilalty pattern number, ie its specification.
The classic envelope is 40 mm in diameter and, excluding the B5 base pins, is 92 mm tall.
