| S/W. Hs.{Lord Ernest Hives - Chair} 81435. re- Anti-freezing Mixture. Cx{Major Len W. Cox - Advertising Manager}6/KW9.1.33. Can you yet please say whether Price's Zero Glycerine is approved for use in our engines ? I usually put anti-freezing mixture in the water of the car I am using in the Winter, and Price's have sent me a tin of their Zero Glycerine which I ordered before I knew that there was any bar by the Works on the use of glycerine. It was reported that Price's were introducing some other chemicals to make it meet with our approval, and I would be glad to know whether there would be any objection to my using this in a 20/25 h.p. R-R, or whether there would be definite technical objections. Cx.{Major Len W. Cox - Advertising Manager} RECEIVED 10 1933 LID{A. J. Lidsey} | ||
