| To BJ. from Hs.{Lord Ernest Hives - Chair} X9930 Hs{Lord Ernest Hives - Chair}4/LG8.2.24. With reference to your memo. BJ12/E6.2.24. We attach a report on the EAC. engine weight. We should anticipate that the addition of front wheel brakes will add approximately 100 lbs. to the chassis weight. There will also be a larger radiator and bonnet which may add a further 20/25 lbs. It is possible, however, that a certain amount of weight may be saved in the new 4-speed gearbox. It is impossible to say definitely at present what this will be. Hs.{Lord Ernest Hives - Chair} | ||
