Leslie} from Rm.{William Robotham - Chief Engineer} e.{Mr Elliott - Chief Engineer} HPS.{Horace Percy Smith - Experimental Factory Mgr} Rm{William Robotham - Chief Engineer}8/R.9.3.38. B.III FRONT SUSPENSION. This is to confirm that you will run the metallic spherical top wishbone bearing on the B.III bumper to prove that it will perform satisfactorily. We expect you to say whether in its present form you consider it to be the best possible design from which to start for this particular type of bearing. Having established that this bearing is available as an insurance policy, we should proceed to get a satisfactory type of rubber bush afterwards. Rm{William Robotham - Chief Engineer} | ||
