| X4247 To R.{Sir Henry Royce} from Hs.{Lord Ernest Hives - Chair} c. to CJ. c. to E.{Mr Elliott - Chief Engineer} c. to Da.{Bernard Day - Chassis Design} c. to BY.{R.W. Bailey - Chief Engineer} Hsl/LG21.7.21. X.4247 - RE GOSHAWK 11 - GEAR BOX. There is no oil filler plug instructed for the Goshawk 11 Gear Box. There is a plug on the top of the gear box which can be used for filling in oil but there is no means of seeing or knowing what the level of oil is in the gear box. A filler plug was shown on LeC.1333 but a note is on the drawing to say that it is going to be altered. We should like to know what method it is proposed to adopt to examine the level of oil in the Gear Box. Hs.{Lord Ernest Hives - Chair} R.R. 3258(100T)(S.H.'798.10.12-20)G.2848 | ||
