| To Hs. {Lord Ernest Hives - Chair} from E. {Mr Elliott - Chief Engineer} c. to CJ. Wor. {Arthur Wormald - General Works Manager} c. to Hy. {Tom Haldenby - Plant Engineer} Da. {Bernard Day - Chassis Design} X4221 E3/M17.2.22. GOSHAWK(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) 11. SLIPPER FLYWHEELS. X.4221. With reference to the above Mr. Royce thinks that we shall have to make these in steel, and bush them on the spigots. This metal should give less trouble as regards running balance, and very possibly will have sufficient damping effect without increasing the dimensions. E. {Mr Elliott - Chief Engineer} | ||
