I note your remarks in regard to the Dunlop pattern of road wheel and that you are of the opinion that the Rudge-Whitworth wheel may prove to be superior, and that therefore attempts should be made to obtain information as to the behaviour of the Rudge-Whitworth wheel during the war. Secondly, you recommend that we should at once design a hub to carry Michelin disc wheels, owing to the high reputation which they have obtained in war service and their general simplicity. I am making enquiries with regard to both of the above points. In the meantime I propose ordering 250 sets of material to the Dunlop type of hub and wheel, which has been standard up to the present. | ||
