VITAVOX B50 ADMIRALTY GUNLAYING MICROPHONE
Here we have a very nice Vitavox B50 25 ohm moving coil microphone from 1959 These were used by the Admiralty in gun turrets on ships of the line. during the late 1950's onwards. These were hand held weatherproof devices of very high quality and the spring pressel switch featured extra contacts for remote control applications - not often seen. Thought to be a new unissued devices but show slight marking commensurate with 50 years or so of storage!
Sensitivity -85dB, Response 60 - 8000Hz.
