| 6000 Experimental Department 28th January 1937. Rm{William Robotham - Chief Engineer}/Wst.12/AP. R.Banks Esq., Ethyl Export Corporation, Thames House, Millbank, LONDON S.W.1. Dear Banks, In reply to yours of the 27th inst., we have never been approached by the Massa Company with any of their sparking plugs, and we certainly have never tested a plug known as the "Marathon". Is this a good plug.? If so, could you obtain one for us to try on our single cylinder engine.? Yours sincerely, | ||
