| BY.{R.W. Bailey - Chief Engineer} FROM DA.{Bernard Day - Chassis Design} ORIGINAL DA{Bernard Day - Chassis Design}3/M7.12.29. Copy to SG.{Arthur F. Sidgreaves - MD} Copy to HS.{Lord Ernest Hives - Chair} 20HP. REAR SHOCK DAMPERS. x5520. Herewith we send N. scheme 2995 shewing the application to the 20HP. rear damper of the spring connecting rod shewn on N. scheme 2994. The details are the same except for the length. It will be seen that the lower end of the rod is rather close on the ground clearance. R.{Sir Henry Royce} agrees to it being tried thus experimentally. Should it be decided to standardise it we shall send you a revised scheme with some more clearance. DA.{Bernard Day - Chassis Design} | ||
