| +4240 To R. {Sir Henry Royce} from Da. {Bernard Day - Chassis Design} c. to Bn. {W.O. Bentley / Mr Barrington} c. to EFC. {E. Fowler Clarke - Electrical Engineer} Extract from- Da {Bernard Day - Chassis Design} 6/CB20.P.21. RE "GOSHAWK(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) 11" - RADIATOR & BONNET. ----------------------------- X.4240. We also send a print of "N" scheme 710 shewing the radiator dimensions, also from LeC.1320. For the mounting of the radiator we have adopted the original scheme on Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) 1. We are not sure whether it is intended to fit ea shutter, a short circuit thermostat, or neither, in view of the expense, so that we have not dealt with this matter on the radiator drawing, but if it is intended to fit either of these arrangement, we would make a scheme adapted from the "Buzzard(Aero Engine)" drawing.
