| - 2 - (c) Rectified bob weights rattling (front bumper). (d) Fitted new rubber buffers to front bumpers. (e) The radiator shutters were rattling, but in view of the urgent call from S stating that the car would be needed for demonstration runs, this rattle was not eliminated. Apart from the details of the report, I have very few observations to make. These are:- (1) The brake drums were not skimmed, owing to the fact that this chassis is an experimental chassis and possibly a report was being kept of the mileage run. (2) On final test after relining the brakes, the brakes were still inclined to pull very slightly to the O/S. (3) As regards "burning in" on road test, there was nothing abnormal in the treatment of this chassis as compared with that of any standard 3½-litre. (4) On delivery (it must be understood here that the Trials Driver from S was waiting for the car) as there was still a very slight brake pull and the car was being used for Demonstration work, the Driver was instructed to use his brakes as much as possible before giving the run. (5) I saw Cx{Major Len W. Cox - Advertising Manager} on the morning after the event. He told me himself that he had done quite a considerable mileage on the Kingston-by-Pass the previous morning before handing the car over for general Trials work and that the brakes and steering were in order. (6) I am given to understand by Mr. Crawford of LH{Mr Haworth} that the brakes were up to standard and that they pulled up dead square before being handed over to Cx.{Major Len W. Cox - Advertising Manager} K/KC. | ||
