| X1204 Hs{Lord Ernest Hives - Chair}/RM.{William Robotham - Chief Engineer}S/KW.28.10.35. Will the Chassis Technical Staff please note that all future chassis tracings should be given "Ra" instead of "He" numbers, commencing to-day with number Ra.1. This is in order to make Aero and Chassis tracings easily distinguishable. A separate entry book has been provided. It would also facilitate the filing of tracings if no smaller size of paper were used than the standard No.1 size (10¼" x 7½").
