We may have to make economies on the Silver Ripple in order to get the price down to our target. One economy may be to dispense with the servo. In order to see what effect this has on the brakes, I should like you to arrange to couple up the pedal direct to the mechanical rear and hydraulic front brake on the Silver Ripple and see what are the best possible results which you can obtain. With the large stiff brake-drums which are fitted to this car and its low performance, it should be possible to use a high pedal velocity ratio without the need for frequent adjustment. One other economy on the gearbox which I want to try, is a plain bearing on the side shaft of the latest Vandervell indium bronze. It would replace the old needle roller bearing. I do not know whether you have a needle bearing box available on which to make the test. If no other transmission is available, I suggest that the box in 3B50, is replaced by an up-to-date one and converted to plain bearings for test on the Ripple.
