15-EX CAR - 10,000 MILES TEST IN FRANCE.

We attach herewith a report from Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} on the condition of the above car after it had completed 6,000 miles.
Rm. {William Robotham - Chief Engineer} is at Chateauroux(French test region) with the object of confirming steering tests under French road conditions.
Comparative tests are being made with the shorter pendulum lever similar to that fitted to 14-EX car.
He is also investigating the frame distortion and the apparent lack [handwritten insertion] of rigidity of the steering column.
Tests are also being made at Derby to see whether any difference can be shewn with and without the frame [handwritten insertion] tie rods, or with and without the rubber engine mounting.
The information on these points is not yet completed [handwritten, struck through] available, and will be sent through later.

Hs. {Lord Ernest Hives - Chair}
