| Hs. {Lord Ernest Hives - Chair} from Mx. {John H Maddocks - Chief Proving Officer} X1518e. Mx {John H Maddocks - Chief Proving Officer} 2/T3.5.27 Phantom Chassis - K.L.G. Sparking Plugs We have now 48 of the 50 Chassis on test which were instructed to be fitted with K.L.G. Plugs. They have not given us any trouble, and so far as we have gone they are quite satisfactory. We have not of course completely tested all the chassis to which these plugs are fitted, and it will be some time before we can do so. As we have used these plugs from the beginning of the Phantom programme on the test beds where they have given more satisfaction than Lodge plugs which were fitted as standard, I do not think the K.L.G. plugs are likely to let us down.
