| To E. {Mr Elliott - Chief Engineer} from Hs. {Lord Ernest Hives - Chair} ORIGINAL Hsl/LG6.1.32. X4342 "GOSHAWK(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine))" STARTER. At the present time, all the Starters which we are using on Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) 11. engines are working with the edges of the teeth rounded off, not chamfered like the ordinary American practice. We cannot say that we have had any difficulty with the rounded teeth and so shall continue to use them. Hs. {Lord Ernest Hives - Chair} | ||
