Wireless Sets No. 19 MKII USA
An example of a USA manufactured, Canadian version
of the famous British Army Wireless Sets No. 19.
WS 19 was a system
of local and/or remotely controlled radio units and control boxes, originally
designed to provide medium range HF communications and intercom facilities
plus short range UHF communications for the crew of armoured fighting vehicles.
It was designed by Pye Ltd in Cambridge, England in 1940.
The design was subsequently
found to be sufficiently versatile to be used in a wide variety of vehicles
and ground applications, and was manufactured in the UK, Canada and USA.
Royal Signals figures show
that a total of 115,000 units were made during the War. The total
service life of this equipment series was from 1941 to the early 1960s.
