| Rm{William Robotham - Chief Engineer} x1729 W/S. To Sg.{Arthur F. Sidgreaves - MD} from E.{Mr Elliott - Chief Engineer} SECRET. E.4/HP.6.3.35. c. Wor.{Arthur Wormald - General Works Manager} Hs.{Lord Ernest Hives - Chair} By.{R.W. Bailey - Chief Engineer} Da.{Bernard Day - Chassis Design} EV.{Ivan Evernden - coachwork} re Cadillac Body. Referring to your memo Sg.{Arthur F. Sidgreaves - MD}9/E.5.3.35, there is no doubt that with the all steel body work the percentage of stiffness supplied by the body is much larger, in fact the Terraplane frame apart from the body can be described as a piece of tripe as far as torsional rigidity is concerned. With regard to the suggestion for strengthening the front part of the coachwork on our cars, we first of all propose to try a simple experiment of leaving out the semi-isolation and bolting the dash and body rigidly together on SpectreCodename for Phantom III. If this is successful it will open the way up for further developments. | ||
