To BY.{R.W. Bailey - Chief Engineer} from Hs.{Lord Ernest Hives - Chair} c. to Mx.{John H Maddocks - Chief Proving Officer} X4425 Hs{Lord Ernest Hives - Chair}3/LG31. 8. 25. SPARKING PLUGS. X4425 X8970 We recommend that we purchase 500 Lodge C. 200 type detachable porcelain sparking plugs. These plugs have been run on experimental cars for some time and have given satisfaction. They have the definite advantage that they can be easily taken apart and cleaned. The only way in which we can prove out that they are going to be consistently reliable, is to order a quantity of them. There is no reason why these XXXX plugs should not be despatched on Phantom cars. Hs.{Lord Ernest Hives - Chair} | ||
