| HPS. {Horace Percy Smith - Experimental Factory Mgr} from Rm. {William Robotham - Chief Engineer} 1020 Rm {William Robotham - Chief Engineer} 4/R.7.10.37. We have now had sufficient endurance running on the Hall's Metal bearing P.III big-ends fitted into existing shells to indicate that this is exactly what is required to get over the present trouble of big-end failures. Will you, therefore, please put in hand a further 12 of these bearings which will be fitted as available to all experimental cars, and certain selected customers and trials cars. Attached is a copy of the note we have written to Hs. {Lord Ernest Hives - Chair} on the subject. Rm. {William Robotham - Chief Engineer} | ||
