This particular battery is a 1.5 volt dry cell, manufactured postwar in Canada by Union Carbide (Eveready) at least as far as the late 1970's.

It appears to be a direct descendent of an identical battery made during WW2 by Willard Battery Company and others. At that time it was known as a Cell, Dry, Type X, Mk II and was used in various combinations in Sigs equipment such as Fullerphones, any number of wood boxed field telephones and the Wireless Remote Control Unit.

Can anyone advise what equipment was still being used in the late 1970's by the Canadian Army, that needed this battery?
