Ignition Coil of Improved design. (See attached sheet) Origin. To facilitate manufacture and improve reliability and efficiency of coil. Experimental Test Report. Three coils of this type have satisfactorily passed through our schedule of ignition coil intensive bench tests, which we consider to take the place of a 10,000 mile test in a chassis, which latter test has proved to be an unreliable test in the case of ignition coils. Road Test Report. Run 12,000 miles on 14-G4 in France. Also fitted to 23-EK run 1,000 miles. 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. Weight of Old Part.
