Sidgreaves - MD} Copy to Wor.{Arthur Wormald - General Works Manager}Hs.{Lord Ernest Hives - Chair} [Strikethrough: EV.{Ivan Evernden - coachwork}EV.{Ivan Evernden - coachwork}] re Cadillac Body. Sg{Arthur F. Sidgreaves - MD}9/E5.3.35 Thanks for E.1/HP.1.3.35. I note that a full report and analysis is being prepared. I note what you say in the third paragraph about the chassis stiffness and torsional rigidity of the body and am surprised to note that the new construction still left 70% as the share of the body work. If that is so with the Cadillac frame and body, one wonders what the percentage is for the all-steel body work on acknowledged flexible American chassis such as the Terraplane. [Handwritten in margin: features] I agree that there is a considerable amount of pressed steel work about the Cadillac body which could not be used with our construction here for individual bodies but at the same time agree with you that there are [underlined: some] that could be used. We shall be very interested to receive your suggestions regarding the front part but we have rather unhappy memories of the sub-frame which was introduced for the P.II which cost the Company a lot of money and produced none of the benefits which we were originally told it would provide. I thoroughly agree that the Cadillac experiment has been well worth while and that it is going to help in improving the complete car, which after all is what we want. Sg.{Arthur F.
