From verso of card: "Under Fire Precautions schemes, the Home Office is issuing to many local authorities light trailer fire-pumps. . . . This pump has the great advantage of being very easily manoeuvered; not only can it be towed behind any motor car, but it is also light enough to be man-handled. It is capable of delivering two useful fire-fighting streams of water, and can deliver 120 gallons per minute at a pressure of 80 lb. to the square inch. The pump unit can be unshipped from its chassis and carried to any convenient position where water is available. Patrol units in built-up areas will be equipped with these pumps, to enable them to deal with any fire in its early stages."
