| 1166. To HPS.{Horace Percy Smith - Experimental Factory Mgr} from Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls}1/MH.{M. Huckerby}10.2.39. JACKS. We have got till next Friday to decide whether we can standardise the new DWS jacks on Wraith 'C' series or shall have to buy the old ones at a greatly increased cost. To mock this up we shall require some lugs welded onto the present alum brackets. The difference in diameter will be made up by wrapping the new jacks in .032 sheet material. Will you please give us all the assistance possible. Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} | ||
