| 1294 To HPS.{Horace Percy Smith - Experimental Factory Mgr} Rm{William Robotham - Chief Engineer}/JBD.{John B. Dixon - Fuel Systems}9/JH.30.12.38. B.V. & B.50 Servo Spring Plates. With the detachable servo the .020 thick phosphor bronze spring plates exert too much load. We have ordered .012" thick plates to overcome this trouble, until these arrive, will you please reduce the width of the outside flange by .150" on all servos now being built up.
