We periodically run into trouble on Production with the Armature Spring on the Cutout, due to the fact that the black-enamelling on such a small Spring is inclined to be in "blobs", and therefore, prevent the proper functioning of the Spring, and we send you herewith a Blue Print of D.72954 - Armature Spring, made in Phosphor Bronze. Will you please order one dozen of these and arrange for them to be fitted to the various experimental cars, so that we might standardise them to do away with the trouble experienced by black-enamelling.
