| X31/7 To Sg.{Arthur F. Sidgreaves - MD} from E.{Mr Elliott - Chief Engineer} E.3/HP.10.4.34. c. Hsr. Hs.{Lord Ernest Hives - Chair} By.{R.W. Bailey - Chief Engineer} By/NW.{N. Walker - Patents} Da.{Bernard Day - Chassis Design} Cx.{Major Len W. Cox - Advertising Manager} re Jacking Independent Wheel Systems. Referring to your memo sg.{Arthur F. Sidgreaves - MD}32/E.9.4.34, it was never in my mind that we should have two types of jack handles on the one car but that the same type of handle should be used for operating both front and rear, even if the type of jack fixed to the rear axle had to be different. Actually Da.{Bernard Day - Chassis Design} has suggested that he thinks it is possible to have a scheme for the rear axle employing the same type of jack suggested for the independent front suspension.
