Bailey - Chief Engineer} from Hs. {Lord Ernest Hives - Chair} c. to RG. {Mr Rowledge} c. to Wor. {Arthur Wormald - General Works Manager} c. to Roy. {Sir Henry Royce} ----------------- Hs {Lord Ernest Hives - Chair} 1/LG2.10.28. ----------------- F.11 CRANKSHAFT IN NITRO ALLOY STEEL. x3865 --------------------------------------- We assume the crankshaft received from Messrs. Firths will be a drop-forged crank made in a similar way to the present standard F.11 crankshaft. We think it would be unwise to test new material with a different method of manufacture in it.
