| To BY.{R.W. Bailey - Chief Engineer} RG.{Mr Rowledge} } FROM R.{Sir Henry Royce} E.{Mr Elliott - Chief Engineer} DA.{Bernard Day - Chassis Design} } c. to CJ. BJ. WOR.{Arthur Wormald - General Works Manager} HS.{Lord Ernest Hives - Chair} X9940 R4/M28.1.24. S E C R E T. RE. EACs. 1. to 5. SYMBOLS AND DESCRIPTION. X.9770 X.9940 The above as given in BY's list of 14.1.24 seems O.K. re. EAC.1. 4-wheel brakes. These should be carried out on a scheme which we should expect would give satisfaction. It should be modified from the original if it is expected that this would not make a really satisfactory scheme. (I think it was the original semi-servo which we have decided is not the most desirable.) I think it should be altered to slow speed all servo, as we are using on EAC.4. & 5. re. EAC.2. Only a few of these should be made, as here again we expect the brakes cannot be made ideal. re. EAC.3. The materials for these standard production chassis should be kept as low as ever possible, so that EAC.4. can be put into production at the first possible moment. re. EAC.4. This is the important chassis, eclipsing all others in urgency, hope, and importance, even making EAC.5. of small urgency if this proves as we expect, successful. R.{Sir Henry Royce} | ||
