WST 7th December, 1934. Messrs. Rolls-Royce Ltd., Derby. For the attention of Mr. H.{Arthur M. Hanbury - Head Complaints} E.{Mr Elliott - Chief Engineer} West. Dear Sirs, We beg to acknowledge receipt of your letter of the 6th inst. and very much regret to note your remarks in regard to the speedometer on Mr. Fedden's Bentley chassis. Mr. Fedden has been well-known to the writer for many years, and we have done a number of quite special A.T. jobs for him, giving him every satisfaction. It does sometimes arise that we have to pack up the mileage drive, but it is, of course, intended that this shall be done in a proper manner. With regard to the threads stripping from the screw, this we have not had happen before, but we have had the thread go in the earlier cases where the alloy was not the same as it now is. It is now of Zinc base alloy, and the thread is far more satisfactory. We presume that it was not the thread of the screw that was faulty, but that the latter had gone in the material. We cannot, however, understand how the trip mileage could be recording twice its proper speed, due to these faults. We feel that this cannot have happened, but that, possibly, the worm was slipping, due to the incorrect meshing with the screw, and that it was only recording half its mileage. | ||
