STAYBRIGHT RADIATOR. ------------------ We have completed 90 hours running on a 20 HP. Staybright radiator to E.55062. In order to reproduce road conditions, steam was passed into the radiator while the tests was in progress to maintain the water at 90°C. No failure of any description occurred to the Staybright soldering. Hs{Lord Ernest Hives - Chair}/An. | ||
