| G.W. Hancock Esq., Hotel de France, Chateauroux, Indre, France. Thank you for your daily report. We note that you say that as the hydraulic tappets are supposed to be right you are not touching them. We must of course know what has happened to these silent tappets since they are identical in design with those that we are proposing to standardise, and which ran 10,000 miles on 28-EX. The main difference between the arrangement of the Rolls-Royce and the Cadillac set is that the Rolls-Royce has a special filter. Will you please let us have the result of your examination as soon as possible, as we shall very shortly be in production with these details here. We note your remarks re the CADILLAC steering. It is no use saying that you want a steering as free from road shocks as the Cadillac and higher geared. The reason that the Cadillac is so good for road shocks is because it is so low geared. You cannot expect to have its virtues without its vices. You will not find that the 25 HP. is as free from road shocks as the Cadillac, all we say is that it is a great deal better than the last steering fitted to this car. In view of your observations about the Cadillac we are putting in hand another Marles steering with a lower gear ratio(6/11 20/25). We quite appreciate the wintry conditions and the unpleasantness of the roads. I think you could with advantage refer in your daily reports to the fact that you are driving the car as fast as 28-EX. Can you give us any opinion on altering the tyre pressures? HE/Rm.{William Robotham - Chief Engineer} | ||
