Origin: To increase amount of friction. Drawing No. X No.4207 Part List Experimental Test Report. At present 40/50 cars have one fibre friction washer in one pivot. It is proposed to fit friction washers to both pivots and change the material from fibre to lead-bronze. Road Test Report. Adopted by Springfield. We have proved that 40/50 chassis when they have been on the road for a time, are improved by slightly more friction in the steering. It has the disadvantage that the customers first impression of a new car is that the steering is heavy. 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.
