| Da.{Bernard Day - Chassis Design} from Hs{Lord Ernest Hives - Chair}/Wst. c. E.{Mr Elliott - Chief Engineer} X6137 Hs{Lord Ernest Hives - Chair}/Wst.1/ADL9.2.32. J.3. and 25 HP. BATTERIES With reference to your Da{Bernard Day - Chassis Design}2/Mll.2.32 we attach one print each of the drawings in question. With regard to battery box lids, acid should not escape from the battery and even if it does, holes in the bottom of the box should allow efficient drainage and the boxes are treated so as to be acid proof. It is impossible to have a moulded lid{A. J. Lidsey} for the proposed universal battery, if we insist on a lid{A. J. Lidsey} we must go back to an English battery not an international type. The battery makers themselves favour a complete battery box lid{A. J. Lidsey} rather than two moulded battery lids. Hs{Lord Ernest Hives - Chair}/Wst. | ||
