| To S. from ROY.{Sir Henry Royce} ROY{Sir Henry Royce}5/MG23.9.33 continued. 2. Doubtless there will be many Rolls owners who will buy Bentleys also, and they will naturally want to use the same oil for both cars. As far as Shell Oil is concerned, I am in doubt as to the policy here. On the 20/25 HP. and 40/50 HP. Rolls Chassis we quote TONNELINE Oils as an alternative obtainable on the Continent, and it is suggested we do likewise with the Bentley. Will you kindly advise. ROY.{Sir Henry Royce} AGREED.
