Before any quantities of these sparking plugs are ordered, the Experimental Department should be consulted. There are one or two modifications which Mr. Royce recommends and also we have discovered one or two faults with these plugs which we are anxious to see whether they are confirmed in general service with the 500 plugs that are out.
