| To Rm.{William Robotham - Chief Engineer} from HPS.{Horace Percy Smith - Experimental Factory Mgr} 2a HPS.{Horace Percy Smith - Experimental Factory Mgr}9/VS.{J. Vickers}31.7.40. As requested, we have produced a new Breech Cross Shaft in new material, S/ZN cyanide hardened, against the one which is now in mild steel, so this should be a very big improvement. I thought you would like to know in case someone raises the question as to the failure. --------------------- HPS.{Horace Percy Smith - Experimental Factory Mgr} [Signature] | ||
