| 1166 To Ev.{Ivan Evernden - coachwork} from Rm.{William Robotham - Chief Engineer} Rm.{William Robotham - Chief Engineer}8/MH.{M. Huckerby}9.2.40. Donald Sessions is going to make us a trunnion mounting for the jack in order to prevent the jack neck being twisted off when the car is inadvertently jacked up without the hand brake being applied. We should like a scheme drawing showing the jack at present fitted, with our latest bumper bar etc. to give Donald Sessions the limitations of the job. Rm.{William Robotham - Chief Engineer} | ||
