| X.4263 Extract from hs {Lord Ernest Hives - Chair} 1/LG23.1.22. X.4219 Front axle. X.4263 We have had one of the Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) original type front axles break in the centre between the two front springs. This shows there is a very little factor of safety on this section with the old axle. hs. {Lord Ernest Hives - Chair} | ||
