ROAD SPRINGS. X.4261.
No. 6. Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) 11. appears less flexible than 4-Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine))-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(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine))-11 was RR. springing and 6-Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine))-11 might be anybody's springing. We must mind we do not get shock dempers which cause harshness, or use too stiff springs.
