| X4050 DUNLOP RUBBER CO.,LTD. TELEGRAPHIC ADDRESS: DUNLOPS, PHONE, BIRMINGHAM. TELEPHONE: BIRMINGHAM CENTRAL 4108 (P.B.E) EXTENSION No. YOUR REF: OUR REF: AGP/HR.5.132. FORT DUNLOP ERDINGTON BIRMINGHAM Messrs. Rolls-Royce Ltd., Experimental Department, DERBY. 13th. February. 1930. Attention of Mr. W.A. Robotham. Dear Sirs, Out of balance of 6" tyres for 19" Rims. Referring to yours of the 20th. Dec. (ref.Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}3/MJ). We shall be glad to be advised whether you have yet made such provision that you can accept tyres up to 67 inch ozs. out of balance. Referring to your last paragraph, we appreciate that the difficulty is partly due to the increase of tyre section. So far as the reduction of diameter is concerned, we think you will be able to agree that this change was affected to meet your wishes, and not that we desired it. Yours faithfully, For THE DUNLOP RUBBER CO. LTD., [Signature] Development Mgr's Office. | ||
