| γ 541. To HPS. {Horace Percy Smith - Experimental Factory Mgr} from Rm {William Robotham - Chief Engineer} /FJH. {Fred J. Hardy - Chief Dev. Engineer} Rm {William Robotham - Chief Engineer} /FJH. {Fred J. Hardy - Chief Dev. Engineer} 13/AP.11.1.37. SERVO MOTOR MECHANISM. Re your HPS. {Horace Percy Smith - Experimental Factory Mgr} 7/VS. {J. Vickers} 8.1.37. We have already standardised in both 25/30 and Bentley all the features covered by the prints which you handed to us and which we return, herewith. We believe that you have already made a servo of this type to G.Dept. drawing for use in 22.G.1V. We do not require any parts made to these drgs. experimentally.
