| To D.A. from E. {Mr Elliott - Chief Engineer} Copy to C.J. " " H.S. " " EFC. {E. Fowler Clarke - Electrical Engineer} Handwritten top: EAC PL Prototype Engines to merge... Handwritten top right: E1/G17/11/20. X.3841. RE "VULTURE(Experimental 6 CYL OHV LONG STROKE / Aero Engine)" CYLINDER HEAD. Referring to drawing Lec.1297 showing the "Vulture(Experimental 6 CYL OHV LONG STROKE / Aero Engine)" cylinder head for over-head camshaft, kindly note Mr. Royce does not desire any further work to be done on this for the present as it is now thought that the valves of this engine must be operated by push rod mechanism.
