Dear Mr. West, With reference to our telephone conversation of this afternoon, I have arranged to have forwarded to you to-night, 10 yards of 40/.010" 7 m/m Ignition Cable. A short time ago we had some little difficulty in obtaining certain raw materials strictly to our specifications, and it was found that during that period the Ignition Cables made were not quite so resistive to the effects of ozone as those of our normal manufacture. This matter has been entirely overcome, and the cables we are now making are, we find, more resistive to the effects of ozone than at any time in the past. I shall be obliged if you will let me know in due course the results of your tests with this sample of Ignition Cable. Yours faithfully, B W Wilkinson DEPUTY TECHNICAL OFFICER British Insulated Cables Ltd Helsby, near Warrington NATIONAL SCHEME FOR DISABLED MEN | ||
