| Y6616 Hd{Mr Hayward/Mr Huddy}/SB.{Mr Bull/Mr Bannister} from Hs{Lord Ernest Hives - Chair}/Wst. c. to BY.{R.W. Bailey - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Wst.4/KT.4.1.33. HALF CHARGE SCHEME ON 25 HP. Answering your HD{Mr Hayward/Mr Huddy}/SB{Mr Bull/Mr Bannister}7/MW.21.12.32. we hope to be able to recommend very shortly the correct value of field resistance to be used, as a result of tests we are now carrying out in the Laboratory We intend to standardize this resistance immediately for existing production, and for replacement on customers' chassis in cases of complaint.
