Bailey - Chief Engineer} /WS.5/MG.7.7.39 as to the timing diagram, in respect of the valve timing, this should be as standard B.V. (memo Rm {William Robotham - Chief Engineer} /Swdl. {Len H. Swindell} 2/WH.6.7.39). The ignition distributor having hand control and single contact breaker together with other characteristics of the unit, necessitates a different flywheel marking from B.V.
