X/5159. 194 Da.{Bernard Day - Chassis Design} From Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} c. to E.{Mr Elliott - Chief Engineer} c. to By.{R.W. Bailey - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}4/MA.25.8.33. Attached is a table showing the increase in weight due to the steel brake shoes. In spite of the fact that the steel shoes have been made without a flexible tip it will be noted that they are 6 lbs. heavier per set than the ones in Aluminium. We do not know whether you can lighten the design any further, but this increase in weight is very undesirable on the Bentley. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
