		| I have been lent a manual called Concise Details of Radio Vehicles, an Air Ministry publication, but dated 1950. 
 It covers many types of radio trucks, but there are two that are simular to my Light Warning Truck,
 
 One refurs to a Type 105 Radio Vehicle, the other a Type 267 mk.1 although this is on a Bedford cab/chassis, the back body is very simular to mine, the body is refured to as a 'type E' stores ref 16a/1672.
