| x788 To Hs.{Lord Ernest Hives - Chair} from Sg.{Arthur F. Sidgreaves - MD} re Brooklands Tests. Sg{Arthur F. Sidgreaves - MD}17/E2.7.30 June 17th - 20th.1930. Copy to Wor.{Arthur Wormald - General Works Manager} BY I have read with great interest Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}1/MJ.25.6.30 and I have to-day seen R's comments. I do not know how you can obtain a comparison with other big cars because it is not so easy to obtain the cars for extended tests of this nature. The main thing seems to me to be to get our own chassis right. I note R's memo. says that EV.{Ivan Evernden - coachwork} suggests we should make one experiment with the shutters entirely removed. I do not quite follow the object of this as, even if great benefit accrued, surely the abandonment of shutters is not contemplated. R.{Sir Henry Royce} will be here to-morrow and I will speak to him about it, but the main point I am anxious about is to know what modifications are going to be made to standard immediately and how soon, so as to prevent our continuing to put out on the road cars which our tests indicate have a very narrow margin on this question of overheating. Whilst on this subject and the question of adequate petrol supply at high speeds, it looks to me as if in future we ought to lay it down as a rule that a speed track test should constitute part of the normal 10,000 mile test. There is, I understand, near Paris a very excellent track of later design than Brooklands, i.e. Monthierry, which we could doubtless use for this purpose. Whilst I appreciate that a large number of our cars are never driven full out for any length of time, nevertheless we must realise and appreciate that many of our customers do so and all our cars ought to be capable of so doing.
