| X3725 Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}2/LG. Expl: Dept: 16th. Sept. 1925. Messrs. The Dunlop Rubber Co., Fort Dunlop, Erdington, Birmingham. Dear Sirs, Vehicle Equipment Section. For the attention of R.{Sir Henry Royce} Lodge Esq. We enclose herewith drawings of Michelin wheel which we have been using. We should be obliged if you would return these. We should like to know whether the Dunlop wheel, when drilled to suit the hub, will give us the same distance between the point of contact of the tyre with the road and the pivot pin produced. In other words, is the dish-in the same? The other point is, shall we be able to fit the 7.25" tyres to the rims you will give us, on these wheels? As we only require these wheels for a test, we wonder whether you could loan them to us. With regard to the wheels of the Hispano type. We do not now think we shall require these. Yours faithfully, | ||
