x rs{Sir Henry Royce's Secretary} G.W.Hancock Esq., Hotel de France, Chateauroux, Indre, FRANCE. From Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}5/MA.21.8.33. I have today wired you as follows:- DODD LEAVING WITH PISTONS AND THREE CONNECTING RODS TOMORROW MORNING TUESDAY. The Works have been working hand to mouth on pistons while they get tools for production. The result was we had none we could send. Thank you for your note re petrol pumps etc., and the sketch showing where you have fitted them. The position seems admirable if the pumps will deliver sufficient fuel under these conditions. You will appreciate that the full magnetic force of the solenoid is available to overcome restriction on the suction side whereas the return spring only deals with the restriction on the delivery side. Therefore if you are short of petrol the only alternative is to increase the strength of the delivery spring slightly. Naturally we want to keep this spring as light as possible so that the danger of flooding is the minimum, and consistent slow running can be obtained. We are rigging up an alternative arrangement putting the pumps on a bracket rising up from the frame in the lower half of the steering column. We shall also try your arrangement. We are making rig tests and will give you all the news we can about the deliveries of the pump under the conditions in which your pumps are working.
