The first 2 pics are of original Civil Defence Corps recruitment posters dating to the 1950's or early 60's. The middle pic was taken in May 1966 at the army school of Civil Defence, Devizes, when Wiltshire were hosting a Dorset Division exercise. This basic field kitchen was made using materials found on site.
The 4th pic of the Auxiliary Fire Service was taken on the 9th March 1963 at Swindon fire station and is "Exercise Four Shires" prior to departure. Among the vehicles that can be seen are Green Goddess Fire appliances, Land Rovers and the Bedford lorry with the large bodywork on the back, far left, is a mobile control unit.
The last pic was taken November 1st 1958 at Charmy Down airfield near Bath and is "Exercise Convex". Again many Green Goddess fire appliances can be seen in this pic.
