Vibrator Unit, Transceiver, Type 21 Mk II, SOE

Extremely rare and interesting genuine WWII British Type 21 Mk II transceiver vibrator unit, produced from July and October 1942.

This type of clandestine transceiver, intended for Special Operations Executive agents and Resistance organizations, was made up of four separate elements: receiver, transmitter, A.C. power unit, and vibrator unit, so that the radio set could be used with batteries -- please note that the vibrator unit is the only component offered for sale here.

Good overall condition.
