6011. Hs{Lord Ernest Hives - Chair}/Wst.11/JH. 24th September, 1936. N.F. Stockbridge Esq., Messrs. AC-Sphinx Sparking Plug Co., Dunstable, BEDFORDSHIRE. Dear Mr. Stockbridge, I have now received six of the X399 plugs off a Bentley chassis with a complaint of misfiring, and it has occurred to me that if you are nearly ready with the aero plugs it would be a good idea for you to come up to the Works to see these X399 plugs and discuss modifications etc. bringing the aero plugs along with you to save time. If you can manage this I shall be available on the Tuesday of next week the 29th instant. By that time too I should have further news regarding pre-ignition of the X399. Yours sincerely, | ||
