| X.4261. Extract from RL/M21.8.22 6.Goshawk.11 X.4219. X.4086. ROAD SPRINGS. X.4261. No. 6. Goshawk 11. appears less flexible than 4-Goshawk-11 It does not ride as comfortably at slow speeds, in fact one would say to some extent we had spoilt the springing of the car, and that 4-Goshawk-11 was RR. springing and 6-Goshawk-11 might be anybody's springing. We must mind we do not get shock dempers which cause harshness, or use too stiff springs. R. {Sir Henry Royce} | ||
