| To DA. {Bernard Day - Chassis Design} From Hs {Lord Ernest Hives - Chair} /Rn. {Mr Robinson} c. to BY. {R.W. Bailey - Chief Engineer} c. to Wor. {Arthur Wormald - General Works Manager} 47410 Hs {Lord Ernest Hives - Chair} /Rm {William Robotham - Chief Engineer} 1/LG11.1.29. 'SS {S. Smith} ' BUMPER CHASSIS. X235 48772 Attached herewith is a complete report on the running of the SS. {S. Smith} chassis on the bumping rig. You will note that the front spring life has been quite satisfactory when run with shock dampers. The new hydraulics with restrictions apparently have a very marked effect on spring life. We want the shock absorbers to stand up with 5 dynamic restrictions because it is the condition which gives us the best car control and steering.
