| 600. To HPS.{Horace Percy Smith - Experimental Factory Mgr} from Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell} c. HPS{Horace Percy Smith - Experimental Factory Mgr}/aH. c. By/Ald.{F. Allwood - Experimental Design} Rm{William Robotham - Chief Engineer}/Swdl.{Len H. Swindell}4/MH.{M. Huckerby}13.5.39. WRAITH OR B.V. DYNAMO DRIVE. Some time ago By/Ald.{F. Allwood - Experimental Design} produced a cheapened scheme of dynamo pinion and drive which reduces the number of pieces required and saves approx. 10/- per engine. The scheme is SCD.1040 and we should like you to instruct that one set be made for trial. We will allocate to which unit it is to be fitted at a later date.
