| X18192 G.{Mr Griffiths - Chief Accountant / Mr Gnapp} Hs.{Lord Ernest Hives - Chair} from BY.{R.W. Bailey - Chief Engineer} BY7-P20.2.20. CHASSIS - IGNITION WIRING AND PLUGS. The O.O. have handed me a sample plug as received from the Gilardoni Sparking Plug Company, who have sent the same on to us with a request that we shall test same. It does not seem to me that one plug is much use to you, but the scheme may be of some interest in the present state of the plug question. BY.{R.W. Bailey - Chief Engineer} | ||
