S E C R E T E.{Mr Elliott - Chief Engineer} A.{Mr Adams} C. It has now been decided by Mr. Johnson and myself that we have 3 types of experimental chassis in hand, namely, EAC.l II and III. E.A.C.I you are already well acquainted with. E.A.C.II is the present chassis with certain modifications, i.e. EAC.l engine, 4 wheels brakes, more gas-tight pedals, speedometer gear drive in the change gear box, a modified frame to facilitate luggage carrier, and many other suggested improvements as can be adapted. E.A.C.III is the present chassis with a small number of improvements and is intended to be the same as taking one of the present chassis off the road and fitting it with 4 wheel brakes, and the more gas-tight pedals, but practically no other modifications, or at any rate only those of a very simple nature that can be quickly fitted. This last is for a model of a possible conversion of the present cars, i.e. those lately delivered. It would seem that as soon as you have received some drawings from BY, much of the work of EAC.III can proceed, that is, we may be able to at once to start building up a chassis. Personally I consider that EAC.III is of the utmost urgency, and shall be pleased if you will do all you possibly can to forward the work. Amongst important things it will require a front axle suitable for front wheel brakes which | ||
