| To Hs. {Lord Ernest Hives - Chair} from Rm. {William Robotham - Chief Engineer} Rm. {William Robotham - Chief Engineer} 10/AP.21.12.36. It would be difficult to imagine a more satisfactory position, than that represented by the attached report. We could not possibly have reached this state of efficiency had we not made use of a proprietary article, the Marston radiator core. We have gained in weight, cost and reliability.
