| To Rm.{William Robotham - Chief Engineer} from HPS.{Horace Percy Smith - Experimental Factory Mgr} 1116. HPS.{Horace Percy Smith - Experimental Factory Mgr}7/VS.{J. Vickers}9.5.40. B.60 CRANKSHAFT RE.869 - INTEGRAL BALANCE WEIGHTS. Further to my previous note in this connection, it appears there is only one set of dies in existence which could be modified to produce the new B.60 shaft with integral balance weights. These are the dies which make the standard Bentley and Wraith stampings EW.912.F. Perhaps you will let us know, therefore, whether you are prepared to have the necessary alteration to the dies put in hand or whether you would prefer to make the new B.60 shafts, RE.869, from slab forgings. ------------------ HPS.{Horace Percy Smith - Experimental Factory Mgr} | ||
