| To Hs.{Lord Ernest Hives - Chair} from BJ. BJ17/H18.8.24. 49940 FOUR WHEEL BRAKES. STANDARDISATION SHEET 9940. I attach standardisation sheets re four-wheel brakes, on the 40/50 H.P. chassis, as I expect you will wish to add to these the reports of the 10,000 miles tests now being run with the springs 12 1/2% stronger than our present standard.
