| ORIGINAL. TO HS.{Lord Ernest Hives - Chair}) FROM R.{Sir Henry Royce} (AT LE CANADELHenry Royce's French residence.) Copy to GJ. [strikethrough]WCR.[/strikethrough] R1/M29.1.26. NEXT 20HP. CHASSIS FOR 10,000 MILES. X5770 [strikethrough]X 5540a[/strikethrough] This I think should wait for a few more parts that have to be tested, (including the con. rods with separate bushes, the design of which E.{Mr Elliott - Chief Engineer} is perfecting here, and will be sent direct to Derby on Monday,) so the important items are - (1) Steering - large worm and slower. (2) Dash with steering support. (3) Carburetter - lighter valve, and I hope increased throat and throttle for more power. (4) Front axle - improved strength against brake torque. (5) Increased effectiveness of front shock dampers. (6) New con. rods, etc. I think the car should be sent to Le CanadelHenry Royce's French residence as a part of its 10,000 miles trial.
