The 6Н2П in Cyrillic has been rendered as 6N2P in Latin for indexing. This is valve from the Soviet era in Russia and CCCP denotes a valve from the USSR. The construction is of a pair of triodes in the envelope.
R J Sutherland writes: Although the Soviet Union had a centrally planned economy, it still had different manufacturers each with its own distinctive logo which appeared on the products. In this case the valve was produced by the Voshod factory and the rocket is the factory logo.
