| O.C. From Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} c. to EY. X3499. Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson}5/MJ.19.1.31. Will you please arrange that all car thermostats are marked with the letter which corresponds to the filling they contain. As it is probable that we shall require different fillings for the American and European conditions this procedure will save confusion. Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} | ||
