Servo for 25-30 HP. 22-0-V.{VIENNA}

We send herewith N.Sch.4735 which shows a stop for the brake pedal applied to the servo instead of to the pedal (see HS{Lord Ernest Hives - Chair}/PJH.11/KW.14.1.36).

This drawing also shows our suggestion for the spring ring bolts to give more clearance than is shewn on RM.{William Robotham - Chief Engineer}37.

N.Sch.4735 herewith.
