| Hs.{Lord Ernest Hives - Chair} from Rm.{William Robotham - Chief Engineer} c. Sg.{Arthur F. Sidgreaves - MD} c. E.{Mr Elliott - Chief Engineer} c. Ey. c. RHC.{R. H. Coverley - Production Engineer} c. Da.{Bernard Day - Chassis Design} 346 Rmll/R.9.6.37. We are circulating a standardisation sheet for the Wraith Wheel Movement on P.III. We had certain difficulties in getting sound forgings when we sent this car to France, and had to accept stampings which were not altogether satisfactory. An examination of the parts on completion of the run revealed forging cracks; that they were forging cracks was confirmed by the Laboratory. It will, therefore, be necessary to take up the question of sound forgings with the Forging People right away, to avoid any trouble on production. Rm.{William Robotham - Chief Engineer} | ||
