| RHC.{R. H. Coverley - Production Engineer} from EFC. X6016. EFC4/ADL 3.1.31. X.6016. TWO-RATE CHARGE SCHEME ON EXPERIMENTAL CARS. Will you please arrange for Mr. Brock to supply us with a further 7 two-rate charge resistances of the 6" variety together with two further resistances with 16" of wire. It is the intention for the time being to change all the experimental cars over to the 6" resistance. FJA. Received & tested 27/1/31. E.FC. | ||
