To suit customers requirements. Experimental Test Report. It has been proved by experience that customers will not change the position of the wheel from side to rear. The only practical place for the spare wheel is to carry them at the side. Special cars which have luggage boxes can have rear wheel. Road Test Report. Side wheel carriers have been fitted to numbers of cars, no need for further tests unless design is altered. Right-hand box: X No. 5600 7600 Drawing No. Part List. A Scrap and replace at all costs, including Chassis already delivered to Customers. B Scrap and replace on Chassis in Works. C Scrap present stock and replace on all Chassis not yet handed to test. D Use existing stock Alteration effective on future Chassis. Table of Costs: Weight of Old Part. Cost of Old Part. 40/50 Chassis £4-2-8, 20/25 HP Chassis £3-15-8 Weight of New Part.
