Date 24.3.28 X No. 8430 Drawing No. Part List Description of Parts. 9.5" PENDULUM LEVER WITH OTHERWISE STANDARD STEERING. Origin. To reduce road shocks and make parking easier. Experimental Test Report. This is exactly the same length of lever that was fitted to 'V' series cars. It gives an over-all steering ratio of 15/1 instead of the std. 13/1. Car at Le CanadelHenry Royce's French residence has a ratio of 16 1/4/1 Road Test Report. Run 2000 miles on 8-EX heavy closed car. 4000 miles on 15-EX in France. Gives a rather better steering all round for the troubles we mostly encounter. Weight of Old Part. Cost of Old Part. £3-13-2 Weight of New Part. Cost of New Part. £3-13-2 Difference per Car.

EP. {G. Eric Platford - Chief Quality Engineer} E. {Mr Elliott - Chief Engineer} | 28.3.28 | Agreed. E. {Mr Elliott - Chief Engineer} Apparently the cure for steering trouble is a low enough ratio and retaining a sufficient measure for self-centering. PN. {Mr Northey} | | CWB. | 4.4.28 | Agreed. CWB. It is understood that with 15/1 ration, 2 1/4 turns of steering wheel are required from lock to lock. HS. {Lord Ernest Hives - Chair} | 24.3.28 | Agreed.
