Wakefield's are sending to you at Chateauroux the drum marked "Rolls-Royce EP{G. Eric Platford - Chief Quality Engineer} Oil". This did not arrive in Derby in time for us to fill the back axle in England. As soon as it arrives in France, we shall be glad if you will drain out the Hi-press oil which is in the axle, and run on this new variety, which continues to be a good lubricant at high temperatures.
