| To RHC.{R. H. Coverley - Production Engineer} from Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} X8774 Hs{Lord Ernest Hives - Chair}/Rn{Mr Robinson}3/LG11.2.27. 10-EX CAR. Will you please manufacture one lever G.74666 for the front brake equaliser shaft of 10-EX with length altered from 2.5" to 3.00". This should be fitted to the car with the new front axle, when it is available. We should also like you to arrange for a fan pulley on this car so that the fan runs at 2/3 of its present speed. The load on the front dampers will require modifying to 90 lbs. down and 70 lbs. up. Also the float chamber should be locked whatever carburetter is fitted. With reference to the .720 nut for this car. We consider that this should be made like that of 14-EX i.e., a good bed but tight. The front of the car will be so light that it will not be necessary to obtain an exceptionally high efficiency. Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} | ||
