Used by RC Sigs heavy wireless sections as high power transmitter and receiver normally for communications from Army to Corps and Line of Communication headquarters but could work long distances when required during operations.

Powered with a 2-kW generator on a trailer which accompanied the vehicle and a chorehorse generator for emergency charging.

Early Design

An early design of the CMP Lorry 3 Ton Wireless (C33) was constructed at R.A. Brand & Company , Manchester (based on the vehicle's Canadian Mechanization Depot (CMD) number in the 20,000 range[1]). It features a body very similar to what became the production body built on a Cab 11/12 chassis.
