| 1097 To Rm.{William Robotham - Chief Engineer} from Rm{William Robotham - Chief Engineer}/GB. Copy to Rm{William Robotham - Chief Engineer}/LAG. Ev.{Ivan Evernden - coachwork} Rm{William Robotham - Chief Engineer}/GB.1/ET.24.9.40. Re your letter Rm.{William Robotham - Chief Engineer}10/Mk.16.9.40. The new Vauxhall mentioned in this letter is a 14 H.P. car with passenger accommodation as roomy as the present Vauxhall 25 H.P. The reason why we make the weight of the Studebaker Champion frame 144 lbs. as against Oy.'s 119 lbs. is that Oy. includes the front cross member with the front suspension and not with the frame. In Vauxhall and Opel cars the front cross member and the front suspension form one unit. For the new Vauxhall Oy. puts down 5 wheels at 65 lbs., i.e. 13 lbs. each. This total is 25 lbs. less than the Studebaker weight. I have written to Mr. Platt to learn how this was to be done. , Rm{William Robotham - Chief Engineer}/GB. | ||
