| To CJ. from Hs. {Lord Ernest Hives - Chair} Y4086 Hsl/Tl.6.22. With reference to the attached, Hy. {Tom Haldenby - Plant Engineer} was given the 10000 mile Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) test to carry through. He had entire charge of those cars and arrangements for running. He made his own arrangements as regards his assistants. I did suggest to him that we ought to try and increase the times for lubrication on the Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) compared with our instructions for the 40/50, because it has already been agreed that the 40/50 instructions are unreasonable.
