| Exptl. Dept. Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} 13/KW. 18th March, 1936. The Earl of Rothes, The IndiaProduction 20 HP. with 4-speed box and Front Wheel Brakes Tyre & Rubber Co.Ltd., Mileage Dept., (Area 'B'), 80, Clapham Rd., LONDON, S.W.9. Dear Rothes, Here is a copy of a letter I have written to Worth re tyres. Thank you very much for expediting the steel body for HawkAero Engineins. The increase in weight of the tyres is undesirable, but we may find that when we get the complete wheel we are not so much down. We shall have to convince ourselves that we are getting something out of this extra weight before we fit it. There is always the bogey of tyre noise in the background. Yours sincerely, Att: Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} 10/KW.18.3.36. | ||
