Wor. {Arthur Wormald - General Works Manager} c.c. to RG. {Mr Rowledge} DA. {Bernard Day - Chassis Design} c.c. to E. {Mr Elliott - Chief Engineer} BY. {R.W. Bailey - Chief Engineer} c.c. to FN. KP. Handwritten: X9450 S E C R E T. EAC. - STEERING. Handwritten: X9450 / X9680 With reference to the steering on PN {Mr Northey} 's car. This car is fitted with the side steering tube exactly similar to the present standard 40/50. It has non-set-up springs. The steering was arranged in this way because on the bump test we had numerous steering failures with the car fitted with radius rods and stiff set-up springs. Hs. {Lord Ernest Hives - Chair} | ||
