Attached are particulars of a proposed new sparking plug which has been submitted to us. We do not know whether you are sufficiently interested in sparking plugs to invite these people to submit a sample to us. The advantage claimed is that the alternate expansion and contraction does not effect the tightness of the joints. Apart from this we do not see that the plug is like to have any advantages over specimens hitherto tried.
