Item is a Fire Extinguisher manufactured during World War 2 for the US Office of Civil Defense. See picture of Civil Defense emblem attached and compare to label. Designed to be used by two or more persons to extinguish incipient fires and prevent the ignition of exposed combustibles while accelerating the burnout of incendiary bombs. The four gallon capacity was the largest quantity of water that two healthy adults could carry for extended periods and distances using the two carrying handles.
The pump was operated by one user while the nozzle was aimed by the other. The galvanized steel cover of a trash bin was to be used to shield the nozzle person from the spatters of molten magnesium thrown off by a burning incendiary bomb. The hose was quite long so that the pump operator could stand upright to work the pump at some distance from the burning incendiary. Nozzles were fitted with a deflector to make a fan spray to wet down adjacent combustibles and gently apply water to the incendiary itself to accelerate it's burnout. If water was applied too forcefully it would penetrate the burning molten magnesium, flash into steam, and scatter burning magnesium thus spreading the fire. The fill opening is large enough to allow resupply the tank with water to continue the operation without interruption until the incendiary had burned out and any remaining fire could be extinguished.
