| S/W Hs{Lord Ernest Hives - Chair} R728 O15/C9.11.32 RECEIVED NOV 10 1932 I am sending you herewith a letter from Mac.{Mr Macintosh} in regard to some special fluid that they put into petrol which is supposed to destroy all the carbon and give more power, better petrol consumption, and so on. I do not want you to take too much trouble in the matter unless you are interested, but I thought perhaps you might look through the attached literature and let me know what I can tell him. C. | ||
