Dear Sirs, With reference to the X399 sparking plugs we are now trying out on our chassis we now require one or two modifications to the same, and we think it would be a good idea if your representative could pay us an early visit in order to discuss these latest modifications. We are also now in a position to further discuss the results obtained with the tests we have been carrying out on the Aero Plugs. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
