| To BY.{R.W. Bailey - Chief Engineer} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} x8005 Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}3/LG3.1.29. RUBBER ENGINE FEET. x7005 We have now received half a dozen sample rubbers from The Dunlop Co. which have precisely the rating we are after, i.e: they give a deflection of .180 under 750 lbs. load. We attach a deflection curve and a table shewing the remarkable consistency of these rubbers. We have asked Messrs. Dunlop to give us delivery of the No.6 compound as soon as they can and we see no reason why these should not permanently overcome our difficulties. Attached is a copy of the latter we have written to The Dunlop Co. so that they may know we can carry on with the 500 lbs. rubbers until they can give us the No.6. compound.
