| Rs. {Sir Henry Royce's Secretary} from R. {Sir Henry Royce} +4565 R5/M15.9.25. GOSHAWK(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) 1. X.3481 X.4263 x.4565 With reference to Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) 1. I want this little chassis fitting up rather differently, which includes smaller dia. of wheels, and I want DA. {Bernard Day - Chassis Design} and yourself to arrange that the front axle shall not turn over. If you are getting any fresh tyres, see that they are one of the small balloon sizes - about like those used on the Morris-Cowley. When this chassis is re-arranged I want to compare it with G.3. This latter is delayed by something beyond my knowledge. R. {Sir Henry Royce} | ||
