| WW LIGHTING SET ORIGINAL To HS.{Lord Ernest Hives - Chair} from E.{Mr Elliott - Chief Engineer} E4/G3/5/21. X/353 RE POGNON PLUGS. We send you herewith an advertisement regarding Pognon Plugs. Mr. Royce would like you to get one or two of these plugs for him to test on the lighting engine down here, which is very exacting as regards sparking plugs. He thinks that although from our point of view the Pognon plug as shewn is not right, it is wise to test this pattern to see if our ideas are right. He also thinks that we should point out to the Pognon people that we no longer use 24 m/m plugs, as quoted for us on their list of models in the advertisement.
