Eric Platford - Chief Quality Engineer}11/H18.7.28. re. Chassis No. 81-RF. With reference to your CWB10/CM/17.7.28. We have received the above car at the Works and attention is now being given to it by the Repair Dept. They are very busy at present, but having discussed the matter with Hm.{Capt. W. Hallam - Head Repairs} an attempt is being made for the car to be attended to so that it can be delivered before the Works Holiday. Will Hm.{Capt. W. Hallam - Head Repairs} please proceed with this work as per CWB's memo above referred to and as per the jobs specified on the test card after the test I made of the car this morning with Mr. Trayner. The engine roughness did not seem at all bad in our test, and at present there is no cotton duck material available for the slipper drive. I am pressing for some of this material to be obtained from the Order Office or from the Experimental Dept. to fix in this car. If, however, this is not available in time we will make sure that the slipper drive is set and adjusted as per our latest practice. With regard to the suspension - cadmium plated springs are to be fitted, preferably the existing springs to be cadmium plated, as it is considered an important feature to ascertain what is the actual effect on the springing made by cadmium plating. With reference to the gear box - unfortunately we have not a very good gear box of this type available, and it has been considered that probably the most satisfactory way of dealing with this job after further trying it, is for the present gear box to be quietened, which the R/D.{John DeLooze - Company Secretary} are now undertaking. The steering of this car you reported on some time ago, was considered by Sales as being very good. This has been well tested and inspected, but we do not consider the steering has any particular virtues over the chassis which we are now turning out. The main advantage may be possibly in the fact that the steering has remained fairly well damped after running some considerable distance, which we consider is due to the fit of the worm and nut, in which there is variation, but we do feel that the fitting of this worm and nut as now turned out, is better and more consistent than it used to be. I suggested that we might to advantage dismantle this worm and nut, but it is not thought wise under the present circumstances of urgency and the fact that we do not wish to upset this steering.
