| To Roy.{Sir Henry Royce} from Hs.{Lord Ernest Hives - Chair} X4425 Hs{Lord Ernest Hives - Chair}9/LG2.7.25. LODGE SPARKING PLUGS. The new type Lodge sparking plugs which Mr. Hopps left with us 3 or 4 weeks ago are working very satisfactory. We should like you to order for us 4 doz. more of these plugs so that we can confirm our tests. We require the type with closed end as we find that these stand more heat than the open end.
