| 1231 W/S. Cx.{Major Len W. Cox - Advertising Manager} from Rm{William Robotham - Chief Engineer}/Gry.{Shadwell Grylls} Rm.{William Robotham - Chief Engineer} Absent. Rm{William Robotham - Chief Engineer}/Gryll/R.23.2.37. WAKEFIELD OIL. In view of what you say in your memo Cx{Major Len W. Cox - Advertising Manager}6/KW. 19.2.36., we agree that it will be as well not to try the new C.W. oil in your Trials cars until we have found out something about it in the Experimental Dept. Some of the supply which you have at Lillie Hall can be used in Lp{Mr Lappin}'s car. After a talk with Sg.{Arthur F. Sidgreaves - MD} and Hs.{Lord Ernest Hives - Chair} this morning they decided not to remove C.W. oil from the Instruction Book, as they do not think many people will now be using it before next winter. This gives plenty of time to say whether it is suitable or not. Rm.{William Robotham - Chief Engineer} | ||
