Our Ref. RLK/NK. General Manager: T.C. SKINNER. DIXON. 29th July 1936. Messrs. Rolls-Royce Limited. D E R B Y. Dear Sirs, For the attention of Mr. Robotham. We are in receipt of your letter of the 28th inst, and are interested in the report on the experimental pump. We are inclined to think that we should be justified in reducing the loading on this to the same as that on the pump which we at present supply to you. This would bring us down to the delivery figures which you obtain between 8 and 9 volts. It would seem that there is an ample margin under these conditions and even allowing for considerable deterioration in the pump and a flat battery, it is unlikely that you would find a hill of 1 in 3½ on which you could obtain the maximum speed of which the car was capable in bottom gear. In addition to this of course, the dynamo in any case would give more than the rated voltage of the battery, and thus we do not think we should be justified in having a higher loading on the pump than this. We notice you report that the pump was tested with air bottles of 3 c.c. capacity - should this not be 3 cubic inches. In any case a benefit is only -1- Which is correct?
