Coverley - Production Engineer} 346 Rm{William Robotham - Chief Engineer}/Les9/R.15.3.37. WRAITH WHEEL MOVEMENT FOR P.III. Re: By/Cgh.{W Clough}1/W.12.3.37. All parts fitted to 35-EX front suspension were made to drawings from the Design Dept. in order to save time the new lubrication system was not detailed in the D.O. The steering lock of 35-EX is 36°. The locks for 32-EX and 33-EX with standard suspension levers are 37° and 38° respectively. N.Sch.5054 has since been issued to increase the lock to 38° with Wraith wheel movement. If it is thought necessary to introduce Wraith wheel movement at D.{John DeLooze - Company Secretary} Series without the lightened top levers and 2° increase in lock, the parts can be identical to those fitted to 35-EX.
