| To Hy. {Tom Haldenby - Plant Engineer} from E. {Mr Elliott - Chief Engineer} c. to Hs. {Lord Ernest Hives - Chair} NOMENCLATURE OF EXPERIMENTAL CHASSIS. Y3548 Re the above kindly note that we understand the four wheel brakes chassis with 40/50 engine should be called the "heron(Experimental 6 CYL OHV 40/50 WITH PNEUMATIC F.W.B. air pump on camshaft, then Servo)", and the next and only other move - the chassis with overhead valves and 4½ engine, should be called the "seagull(Experimental EAC.1 aka Export chassis, Phantom I engine)".
