The nearest scheme would be to prepare the chassis for EAC.11. engine, then modify crankchamber of present engine about the rear engine feet so as to fit EAC.2. engine mounting but we concluded this would hardly be a profitable solution, and not early enough. Any present chassis by going to the Works could be altered and fitted with an EAC.11. engine. Naturally it would be costly and spoil some paint, and unless frames were changed there would be many holes in frame without bolts. Otherwise there would be no difficulty and the instructions we are now given are the best ones to adopt (i.e. the only ones we yet know of.) DA.{Bernard Day - Chassis Design} received a memo. from BY.{R.W. Bailey - Chief Engineer} last night to say EAC.11. dash, radiator and bonnet were to be used. Naturally this would be slightly easier for us, but it would upset the coach-builders, and possibly the stock of dash, and bonnet materials. Really I think it hardly advisable. The chief advantage to us is the autovac tank, but I should prefer to use the scheme we have nearly completed which will make all the crossbreeds alike - i.e. these of 'V' series, and any of 'U', or earlier ones, that may be altered to appease buyers. Could not 'W' series be EAC.11. exactly? If not, then let it be like 'V' series, but with EAC.11. radiator, dash and bonnet. We want to get going on EAC.2. because with this we have altered the side levers to facilitate coachwork, and especially the underframe. R.{Sir Henry Royce} | ||
