On the 11th. of September we passed the Lodge Sparking Plug Co. an order for 3,000 model "K" plugs, fitted with 20/1000ths. annular spark gap, and they have now sent the whole of these in. We wish to know whether a further supply of this model of plug must be ordered. We referred the matter to Mr. Platford, who states that it is one for the Experimental Department to decide. It is important that we have a decision immediately, as otherwise the present supply of sparking plugs will be exhausted before fresh supplies can be got in.
