| Hs.{Lord Ernest Hives - Chair} E.{Mr Elliott - Chief Engineer} from R.{Sir Henry Royce} DA.{Bernard Day - Chassis Design} BY.{R.W. Bailey - Chief Engineer} c. to HY.{Tom Haldenby - Plant Engineer} Wor.{Arthur Wormald - General Works Manager} 75080 Rl/M27.3.28. 20 HP. X.3770 X.634 X.3080 X.5010 X.3531 Owing to the improvements (Hs{Lord Ernest Hives - Chair}/Hn{F. C. Honeyman - Retail orders}'s report) made by our competitors - amongst them Buick and Sunbeam - we must really push forward our own progressive development - i.e. India 3. We must get better performance and greater simplicity - i.e. better value for the cost. It means a straight through carburetter, and I shall send to S. by the end of the week what I have done, but we must not wait for this. We are getting a lower top gear by reduced size of wheel: is this sufficient? I am distressed at the moment of complication we are adding with the central oiling. We must work hard to do it a nearer way, or make the parts so that they do not need oiling except once a year, as the Mechanic's joint. Find out what our competitors do, and let us not do any more, because it does not make the performance of the car any better - i.e. max smoothness, acceleration etc. It may do something to decrease the wear. Since we are in trouble with owners reaching the master period, can we not at once prepare for putting in the 37% stiffer crankshaft with oval webs, pending 10,000 miles test before these would be delivered. Will HY.{Tom Haldenby - Plant Engineer} please note that this does not affect conn. rods, and by putting periods up say 18% in revs. get our master period beyond reach. It is madness not to do this at once: I will be responsible. We must not wait for too ambitious a programme, unless we are at once putting the important improvements into production on the understanding that they will be proved by jumper and 10,000 miles tests long before these chassis will be delivered, and they are either stronger, or have been tested on Phantoms, or in slightly different form, and they replace something not quite satisfactory.
