| AJL. From Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} x7772. Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson}3/MJ.16.4.30. OILS FOR LEFT-HAND AMERICAN CHASSIS. We want to use pure mineral oils that are obtainable in the States, in the left-hand American chassis. For the rear axles we have already proved that Whitmore's compound, which is easily obtainable in the States is the best we know of, and therefore what oil we use in the American back axles does not matter. On 24-EX, therefore, will you run the engine on B.B. oil, Vacuum A in the centre point lubrication system and Vacuum B.B. in the engine. We shall have to obtain these oils from Sanderson & Holmes for the first car. Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} | ||
