In addition to this fault, the only other complaint we know of with the Delco ignition is the apparent want of life in the distributor, owing to the steel contact running on the bakerlite. The only exception we have had of this fault was on the Packard, where a carbon contact was used. It will be observed that the Bosch distributor has many fits before one comes to the jump spark distributor, and it is impossible to see what the clearance is, this being the same fault as was condemned by the Admiralty experts in connection with the Remy distributor. In consequence, it will be seen that possibly from a technical point of view, we are in advance of the Americans, but we have never got into the swing of manufacture that would enable us to adopt sheet metal pressings, bakerlite, and ebonite moulds, and die castings to anything like the same extent.
