Swindell} c. to Rm{William Robotham - Chief Engineer}/FD.{Frank Dodd - Bodies} Rm{William Robotham - Chief Engineer}/IMW.{Ivan M. Waller - Head of Chateauroux}8/JH.4.5.39. B.V. ENGINE NUMBER IDENTIFICATION PLATES. Will you please arrange for these to be fitted on top of the water pump boss with the lower edge of the plate towards the front of the car. This is to render them visible with the new fixed side bonnets. The action should apply to existing engines, as and when they come into the shop, as well as new engines. This is actually the position used by production for some time past for Bentley and Wraith engine numbers. Rm{William Robotham - Chief Engineer}/IMW.{Ivan M. Waller - Head of Chateauroux} | ||
