| X. 2641. Extract.-R4/W18816. RE CAR MANUFACTURE. In the starting equipment, the whole of which it is agreed we make, except the batteries, the winding will have to be modified for the 6 volts and twice the current and the magnetic switch for the new pattern, and single brass button, should be made up at once, so as to be proved thoroughly before manufacture. | ||
