With further reference to the coil I find that the separate trembler will add to the wiring so we must, therefore, keep the trembler and the coil together. At home we had designed a small compact coil especially for being enclosed in metal case, which demands a specially designed magnet circuit, and therefore, altogether different design to the present one. I now propose to locate it under the bonnet, just over the steering box, by removing some of the parts which are removable. Yours sincerely, | ||
