Modified Brake Equalising Gear for Servo Rear Brake. 7. Distributing Equalising Gear for Servo. 8. Equalising Gear for Front and Servo Brake. Modifications to Gearbox to introduce Servo Control. Fromthe foregoing I think it will be appreciated that once a car has been sold and built up with a body it will be practically impossible to make such a car into E.A.C. 2, except by very heavy expenditure, whereas it does appear to be a reasonable matter to make such a car into E.A.C.3. and this is precisely the point that one is worried about and upon which I have not sufficient information to know whether Sales policy involves the first or second of the proposals. If Sales policy seriously proposes to sell a car and possibly to have this fitted with a body in the interim and then to transform this car into E.A.C.2. type, then I am afraid it must be agreed that the proposal is impracticable. We have instructed the Exp. Dept. to continue to produce both E.A.C.1. and E.A.C.3. as otherwise we shall do what we have done on several previous occasions, namely, to get almost within touch of obtaining the necessary information on a problem and then suddenly stop the work with the result that we have nothing to shew for the expenditure. Both E.A.C.1. and E.A.C.3. are valuable experimentally whichever road we finally take, and it seems to me in any case that E.A.C.3. is the only practicable scheme into which a standard 40/50 chassis could be trans-formed. Possibly you have later and definite information which would absolve the position as I have outlined it above, but if this is not the case then I think it is certainly worth while putting the facts of the case before CJ, so that they will fully appreciate what is meant by attempting to produce E.A.C.2. from a finished standard 40/50 car.
