| -2- Hml/R.9.11.38. We are urging our experiments on the vacuum-assisted change to give Hdy{William Hardy} the necessary information to complete his schemes. Apart from these installation drawings, there is one other design which is outstanding, and that is to simplify the servo to take advantage of the hydraulic operation of the front brakes. We should be glad if this could be proceeded with as soon as possible. Rm.{William Robotham - Chief Engineer} | ||
