Bailey - Chief Engineer} [crossed out] ORIGINAL 30 40 30 R6/M29.8.27. Z re. BATTERY IGNITION POINTS. X4652 X2694 Why talk about platinum points. Tungsten is what we want, and others have succeeded with. The last thing I pointed out was the copper connection (instead of steel) between the rocker and condenser (no reply.) There is nothing in the little steel finger apparently there to prevent the sides from coming together (lock the bush in.) Have you a current diagram shewing if the characteristic of the current is different, through resistance of the contacts or connections, or bouncing of the contact, etc. Are we to understand that the American Bosch is somewhat better than ours, but worse than Delco? Now some definite progress must be made with this subject, or we must give it to someone else. MADE AT CROXLEY R.{Sir Henry Royce} | ||
