This is the famous WS19 used in numerous soft skinned and armoured vehicles from 1941. The Transceiver “A” set covers 2.0-8 MHz with a output of about 2.5 watts AM &. 5W on CW. There was also a VHF FM “B” set covering 229-241MHz with 400mW output for short range use and an Intercom for crew communications.
The pictured shows the Canadian MkIII version with Cyrillic legends. These were manufactured by RCA and other companies, as part of the lend-lease scheme for allied Russian forces. The B sets were often removed during workshop refurbishment after WWII.
