| -2- HK{Col. T. Harker - Sales}2/G27.7.20. Contd. large number of radiators with brass tubes which, if they are defective, should be stopped at once. Whatever is correct for U.S.A. is correct in England and other parts of the world. We believe that much of the water supplied for filling radiators is either slightly acid or slightly alkaline, and we are investigating whether they is any material advantage in using copper".
