| To CJ. from BJ. BJ17/H15.7.24 (Cont'd.{John DeLooze - Company Secretary}) -2- allow the chassis to bump on the axle at very high speed on French roads. Perhaps this was good, because it would indicate to our comers that they must not drive so fast on bad roads, and the only alternative was to fit all our cars with stiffer springs, which would be comparatively uncomfortable on good British roads. It seems a pity to spoil the springing of all our cars on British roads, for the sake of making them suitable for running on bad French roads at very high speed. Under these circumstances, it is therefore probably better for us to take our demonstration cars as our standard for cars to be delivered in England, and fit stiffer springs for France. *Cars to be used always in* From the above it will be seen, therefore, that:- (a) We cannot give a definite opinion until the back of the open car has been upholstered, and then we hope the Sales officials will be able to try it. (b) We cannot give a decided opinion on the closed car until the back springs are the same as our demonstration landaulet, when we hope the Sales officials will be able to try this. The landaulet can remain in London for an indefinite period. The touring car is required back at Derby as early as possible next week, as they wish to examine certain parts following its run of 10,000 miles in France. B.J. | ||
