| 354 To Rm. {William Robotham - Chief Engineer} from Sg. {Arthur F. Sidgreaves - MD} re P.III Valve Gear. Sg {Arthur F. Sidgreaves - MD} 11/E12.1.37 Copy to Hs. {Lord Ernest Hives - Chair} E.Bl. I am in receipt of Rm. {William Robotham - Chief Engineer} 2/R.11.1.37. I quite agree the recommendation made provided the others concerned agree. This modification, I understand, will overcome top over-oiling but it does not of course deal with the excessive oil consumption complaint xxx about which I wrote to Hs. {Lord Ernest Hives - Chair} separately the other day. We will discuss this latter point at Derby next week and I hope suggestions for overcoming it will be available. We must also discuss at the same time the question of whether the modifications set out in Rm {William Robotham - Chief Engineer} /Swd11/R.11.1.37 should not be made the subject of a Depot Instruction Sheet.
