BARTLETT. DUNSTABLE BEDFORDSHIRE [LOGO: THE SOCIETY OF MOTOR MANUFACTURERS & TRADERS LTD.] OUR REF. NFS/GEB. YOUR REF. CONFIDENTIAL. 15th June, 1936. Messrs. Rolls-Royce Limited, Derby. For the Attention of Mr. H.{Arthur M. Hanbury - Head Complaints} E.{Mr Elliott - Chief Engineer} West. Dear Mr. West, Further to our talk during my recent visit re. aircraft sinterkorund plugs, I enclose herewith blueprints of our drawings X410 and X412, showing the plugs we are proposing to make up for you for further test. The drawings are to scale, and before we proceed I shall be glad if you will examine them from the point of view of the external dimensions and let me know whether they will meet your requirements for further test. The two plugs are identical except for the length of the insulator nose, and if you will agree the external sizes, we will arrange to make up fourteen of each as arranged. As far as the internal construction is concerned, will you please regard the details as confidential. It will naturally take us some little time to make up the insulators required for these tests, but upon receipt of your reply we will proceed without delay. Yours faithfully, N.F. STOCKBRIDGE, Managing Director. Enclosures: 2. MAKERS OF AC SPARKING PLUGS - AC AIR CLEANERS - AC PETROL PUMPS - AC PETROL GAUGES - AC OIL FILTERS - AC OIL GAUGES | ||
