| HOX. & Hs.{Lord Ernest Hives - Chair} from Mr. X198e- Hx2/T5.3.27. re KLG. Plugs. With reference to your enquiry as to the suitability of the above plug for the Phantom Engine, so far as our experience goes, we have found them quite satisfactory. In fact, some time ago, when we were in trouble with overoiling on the Phantom engine, we considered the K.L.G. Plug to be definitely better than the Lodge. As we are not suffering from this trouble at the present time, this point does not greatly concern us. RECEIVED | ||
