Dear Sir, We would be grateful for your consideration in a matter concerning the recent tests conducted by your Research Engineers with our product. It is customary for Sparking Plug Manufacturers to issue charts, catalogues and other informative literature indicating the plug types approved and recommended for the various makes of motor. As this information must be of the most accurate and up-to-date character, Motor Manufacturers usually test and approve sparking plugs for their engines, authorising the plug makers to use the phrase "Officially Tested and Approved" in the literature referred to above. As the tests recently carried out by your Engineers on Champion Types NA{Mr Nadin}-8 and LB-8 were, we understand, entirely satisfactory, we would be glad if you would extend to us the customary permission to use the above phrase in our charts, catalogues, etc. Awaiting the favour of your kind reply, we are, Yours truly, CHAMPION SPARKING PLUG COMPANY LIMITED [Signature] SECRETARY ALL STATEMENTS OR AGREEMENTS CONTAINED IN THIS LETTER ARE CONTINGENT ON STRIKES, ACCIDENTS, FIRES, OR ANY OTHER CAUSES BEYOND OUR CONTROL AND ALL CONTRACTS ARE SUBJECT TO APPROVAL BY THE SIGNATURE OF A DULY AUTHORIZED EXECUTIVE OFFICER OF THIS COMPANY.
