| To EH. from R.{Sir Henry Royce} Contd. (7( The battery was found to have lost nearly all its electrolyte in some cells, suggesting some better management at the Works in looking after these cells, as this is the second time a car has arrived here and given rise to inconvenience before the cause of the trouble was found (suggest also smaller charging current when E.M.F. rises. Leak since found in wiring. (8) X.3461. The rear shock absorbers are a certain improvement, and should (if proved to be sound) be fitted at once, I have agreed to fitting them on the trial cars without the 10,000 miles certificate, and since they are not likely to cause accident provision should be made for fitting them on all cars, and the unsuitable tanks put into stock for repair cars. This class of shock damper is suitable for the rear of any car fitted with cantilever springs i.e. spring naturally having less friction) With these fitted the springing can be slightly softer than our former standard, owing to the reduced oscillation resulting in less risk of bumping (but slightly too soft springs were fitted to 1.EX. (9) Let the next car that you send be lubricated with Castrol. We assume that 49 GB is lubricated with Castrol, but the engine is still so tight, that any virtues in the Castrol will not have been apparent. (10) X.3437. Re cylinder lubrication we are suggesting that current cars shall be sent out as pre-war, but with the extra oil valve pressed down with a special metal fitting, which can be easily removed if we find the practice bad, but it is highly desirable to have as much oil on pistons as possible for sweet running, freedom from piston noises and absence from wear.
