| -2- Hs {Lord Ernest Hives - Chair} /Rm. {William Robotham - Chief Engineer} 1/KW.23.4.36. (4) We are proposing to send 32-EX to France next week with the rubber mounted body and the rubber between the axle and the road springs. It may be possible to arrange for the rubber shackle pieces to follow the car out and be fitted when some miles have been covered on the car. We ought to get some experience of the final production scheme here before we start running endurance. We were not very impressed with the directional stability of 36-EX on the run down to London on Monday. Of course this is an altogether bigger body than 33-EX. With reference to the tyre side of the job, we had a discussion with Mr. Healey, the Works Director of the Dunlop Rubber Co., on Tuesday. They have been doing a number of tests and are submitting some tyres to us this week which they think will have a better life than the Dunlop R.90 type, and with equal silence. If these are satisfactory we can send them out with 32-EX. We note your reference to floorboards in Sg. {Arthur F. Sidgreaves - MD} 14/H.21.4.36. We carried out some tests on 36-EX before it was sent to London, damping the floorboards with large pieces of lead. We also compared it with 30-EX as far as we could, which has wooden floorboards. As a result of these tests we came to the conclusion that these had not a large bearing on the problem. We hope that Hoopers will not be long in making their floorboard alterations because with 32-EX going to France, and 34-EX in MX {John H Maddocks - Chief Proving Officer} 's hands being prepared for demonstration purposes, we are once more left in the position where 33-EX is our only car for all experimental work.
