| Y56 44706 No. .2. V.O.Co., Ltd., to Messrs Rolls Royce Limited We also wish to confirm that MOBILGREASE NO.5. is suitable for the bearings of Motor car dynamos, etc., where a soda-base grease of this kind is required, because of its higher melting point, in comparison with the normal lime base grease as used for water pump and general chassis lubrication. Yours faithfully, VACUUM OIL COMPANY, LIMITED. O.{Mr Oldham} Javes Chief Engineer. OTJ/ND | ||
