Re 19 Armoured Cars for India(Production 20 HP. with 4-speed box and Front Wheel Brakes). Replying to your BY {R.W. Bailey - Chief Engineer} /C3/H17-3-21, we think it would be safe to proceed with the hubs as shown on "N" Scheme 784, especially as the approval of the India(Production 20 HP. with 4-speed box and Front Wheel Brakes) Office may take some little while. It will be noticed that the hub is the standard artillery type, except for the size of the bolts holding the wheel in position, which have been increased to ½" at the request of the tyre makers. Three prints of N Scheme 784 herewith. Hs {Lord Ernest Hives - Chair} MAR DA. {Bernard Day - Chassis Design} RECEIVED | ||
