To attain consistent damping. Experimental Test Report. Fitted to 10-G-111 and run 10,000 miles in France. Road Test Report. These have worked satisfactorily after alterations reported. Brackets for rear have withstood the strain imposed. Guards prevented damage by stones etc. Poundage has remained consistent. [Checkboxes] A Scrap and replace at all costs, including Chassis already delivered to Customers. B [X] 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. Weight of Old Part. Weight of New Part. Difference per Car.
