Here is my example of this WW2., lantern, it consists of the usual steel tank and hanger and the burner's air buttons are also made of steel. I have fitted it with an almost all steel pump, the pump rod is made of brass and so is the bottom end of the pump tube, as is the part which holds the return valve washer. I also fitted the military GF control cock, this control cock has a brass knob and the thread which the gland nut screws onto is made of steel, the control cock was originally painted silver grey, but the paint job was knackered. I have left a little of the original paint on the brass knob. This lantern's original paint job was that silver grey colour, but it was to far gone so I have repainted it, Jeff.
