| X1812 C. Hs.{Lord Ernest Hives - Chair} I am handing you herewith two special sparking plugs that have been sent to me from Paris. The Plugs in question are specials; in fact they appear to be so special that one very much doubts their utility. In any case, however, it is advisable that you should examine same and let us know what you think of their possibilities. On the face of them, they seem open to several objections. BY.{R.W. Bailey - Chief Engineer} | ||
