Bailey - Chief Engineer} from Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer} c. to DA.{Bernard Day - Chassis Design} c. to R.{Sir Henry Royce} X5450 Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}2/LG19.1.27. 20 HP. SIDE STEERING TUBE SPRINGS. X5450 Further tests on 20 HP. side steering tube springs have shewn us that the springs F.54759 of 600 lbs. rating give quite satisfactory results fitted up to N.sch. 2308. We therefore propose to standardise these springs as soon as we have completed bump and road tests and suggest that orders should be adjusted accordingly.
