| (2) frame, and the P & R battery on the runningboard where-ever it can be used. With EAC.5. we come to the first car in which there will be a chance of ample room for the battery in the frame, and we propose to make it possible to use a 75 amp. hour battery in that position, but of course this car is some considerable way off, and this proposal cannot affect production at the moment. We have as you know been in communication with Mr. Minchin on the subject of the P & R batteries, and the matter was left with the understanding that P & R would produce a 75 amp. hour battery of approximately the same weight as the standard Exide battery and of approximately the same dimensions but at the time I did not realise that these dimensions when it comes to fitting in the frame are really larger than Exide because we are prevented from using a sheet metal box. Mr. Minchin was going ahead with moulds for this battery and I supposed that the whole question was settled up. Perhaps you could tell us more about this.
