| 1235 W/S. To H.{Arthur M. Hanbury - Head Complaints} from Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls}7/MH.{M. Huckerby}1.7.38. CHASSIS LUBRICANTS. Thank you for your H.4/H29.6.38. As no trouble can result from mixing any or all of the oils recommended in the instruction book we agree to the suggestion in the third paragraph of your memo. We think this might remove a lot of ill-feeling among some of the oil companies. Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} | ||
