| X 1435. W/S. {Derby Works / Sales} H. {Arthur M. Hanbury - Head Complaints} From Hs {Lord Ernest Hives - Chair} /Lid. {A. J. Lidsey} Hs {Lord Ernest Hives - Chair} /Lid. {A. J. Lidsey} 6/MJ.30.11.32. ANTI-FREEZING MIXTURES FOR CARS. With reference to the last paragraph of H.8/H28.11.32 we believe there is no intention to market any preparation similar to Prestone or to do up in tins Ethylene Glycol or Di-Ethylene Glycol. We believe the Prestone patent prevents the use of any of the Glycols as marketable anti-freezing mixtures. Hs {Lord Ernest Hives - Chair} /A.J.Lidsey. | ||
