This is a part made for an 1967 austin cooper S in 1979 by me. It was used to keep the car engine cool as they were notorious for cracked heads and overheating. It consists of a gallon jug filled with water, a rubber 2' rubber hose connected to the top of the jug, a rubber hose from the jug to a copper tube with holes drilled at 1/2" spacing mounted in front of the radiator. You simply blew on the hose connected to the jug and water would be delivered in front of the radiator cooling it off just enough so that the car would not go into the red. Repairing the head made this item obsolete :) My twin brother came up with the name the first time we used it on a fishing trip.
