STEERING ARTILLERY WHEELS. X.4586 X.9820 We send herewith N.sch.1321., shewing the above wheels for front and back axles. We believe we can have the steel wheel more or less what we like and we have accordingly altered it to suit the job. If this is not so we should like to know as soon as possible, as this partic-ular design depends upon our being able to modify the Wheel. We shall however be sending you probably tomorrow an alter-native design on the lines of the present Dunlop scheme which will not modify the Wheel. We expect that a choice will be made between the two in the course of a short while. It will be noticed on N.sch.1321., that we ask you to modify the brake drum, and for a slight modification on the pivot. We expect that neither of these will give you any trouble. On the back wheel we want you also to slightly modify the brake drum, but the rest of the gear is like the existing wire wheel arrangement. It will be noticed that we shew two alternative methods of making the hub cap on the rear wheels. If you have any definite choice we should like you to make it, but we think that the type shewn in the lower view with washer enclosed is perhaps the more practical. The scheme of a slipping washer which is pinned to prevent it rotating, but otherwise can find its own position, is an improvement on the Michelin device which Mr. Royce would like you to take out a limited patent for, if possible, in his name.
