To do our water colour we would like a model of the wireless control unit which you have illustrated on RB.{R. Bowen}13004. In the position in which it is shown, it would appear to be very difficult to operate, the control knobs being so close to the capping. With respect to the heater control it is suggested by Rm.{William Robotham - Chief Engineer} that we should follow the policy of other small car manufacturers to have a switch on the heater and no rheostat. This is made possible by the fact that on the small cars the size of the heater relative to that of the body makes it such that if heating is required, one needs the heater full on to. Until the above points have been cleared up it seems a pity to spend any time on making a water colour illustration. We thank you for the loan of the sample of woodwork which Mr. Allen is picking up at lunch time. Ev.{Ivan Evernden - coachwork} | ||
