Rm{William Robotham - Chief Engineer}6/R.8.11.37.

Experimental tests indicate that a marked improvement can be made in the steering by a slight modification at the angle at which the yoke pieces are machined.

The attached drawing shows what has been done.
We have asked HPS.{Horace Percy Smith - Experimental Factory Mgr} to ensure that the first six Wraith cars are machined to this drawing, but would like you to put the instructions through in an official manner.
