| X.4239. To Da.{Bernard Day - Chassis Design} from E.{Mr Elliott - Chief Engineer} c. to CJ. c. to Wor.{Arthur Wormald - General Works Manager} c. to BY.{R.W. Bailey - Chief Engineer} c. to Hs.{Lord Ernest Hives - Chair} c. to EP.{G. Eric Platford - Chief Quality Engineer} E5/M11.5.22. GOSHAWK 11. CONTROL GEAR. X.4239. We send you herewith drawing No.LeC.1574. This drawing shews 2 modifications to the control gear. (1) Length of the toggling lever for the hand control decreased from .9 to .6. (2) The angular position of this lever altered until it is now absolutely toggled. The net effect of these 2 modifications is to open the throttle only 25% (angularly) with the full range of the hand control, and to provide a still more gradual opening effect at the beginning of the movement.
