| [Handwritten note at top] Swall - Please make out a sheet for me to sign - Rm.{William Robotham - Chief Engineer} [Handwritten initials top left] Ido To BY.{R.W. Bailey - Chief Engineer} & Rm.{William Robotham - Chief Engineer} From RHC.{R. H. Coverley - Production Engineer} c.c. to Hs.{Lord Ernest Hives - Chair} c.c. to HPS.{Horace Percy Smith - Experimental Factory Mgr} 4¼ LITRE BENTLEY MAIN BEARINGS. With reference to BY.19/G.18.11.37 the question of Bearing clearance is even now not clear because it is understood that White Metal Thrust Bearings are to be introduced on which crankshaft clearance will be .0025. It is further understood that the remaining bearings in AC.7 are to be given the same clearance as White Metal. A decision however must be made on the question of clearances now the combination referred to is being introduced because we are proceeding to assemble engines for test. Will you therefore please let us have definite instructions. RHC.{R. H. Coverley - Production Engineer} [Signature] | ||
