| Secret and Confidential To R.{Sir Henry Royce} From Sg.{Arthur F. Sidgreaves - MD} Sg{Arthur F. Sidgreaves - MD}16/E5.2.31. - 3 - On this question of a 12 cylinder the first important step seems to be to buy one and you will have received memos, recommending the purchase of a 12-cylinder Cadillac, which I understand is a 6.3 litre car. We could get delivery of one of these very quickly and we could also make sure that Cy. who, you know, is with the Cadillac people, would make sure that we got a thoroughly satisfactory and representative model of the type. You refer in your telegram received about the same date as your letter to high revolutions bringing almost insurmountable difficulties and recommending a higher back axle gear ratio. On the former point you will see that we ought not to admit that high revolutions are impossible because of what we know our competitors have done, and in regard to a higher gear we feel that this would be a retrograde move because it would decrease our acceleration, which after all was one of the main advantages claimed for the Phantom II when first introduced, and here again we must remember that, when on N's visit to America he was asked to demonstrate the points of improvement on the P.II as compared with the P.I the result showed that the acceleration performance from a standing start of their P.I was even better than the P.II Your letter and telegram also referred to the necessity of a double top as early as possible, and on this point you will remember that I have been saying for 12 or 18 months that we must have an easy change scheme at the earliest possible moment. I understand that Derby are pushing on with this work and Wor.{Arthur Wormald - General Works Manager} hopes to have two of your different schemes ready for test by the end of May. It is very important that we should have something in this direction available in time for the Show this year. In fact at the begining of 1930 I was definitely of the opinion that we ought to have something of this sort to offer in 1931 but unfortunately we are still without it. | ||
