Engineer}4/AP.23.11.36. P.111 and 25/30 STEERING GEARS. We are sending over to Mr. Brock's Department a 25/30 HP. Steering which we have built up in accordance with our recommendations for set up load. We suggest that you should retain this gear as a standard of comparison to which all Production Ph.111 and 25/30 gears should be set. The gear is set to the high limit of 1 1/4 lbs. on the steering wheel rim which is the figure we prefer. Rm{William Robotham - Chief Engineer}/FJH.{Fred J. Hardy - Chief Dev. Engineer} | ||
