| 200* HOTEL DE FRANCE. CHATEAUROUX(French test region)?. Indre. France. Rm {William Robotham - Chief Engineer} /GWH {George W. Hancock - Head Chateauroux} /IMW {Ivan M. Waller - Head of Chateauroux} /7/JAB. 20th April 1937 To. Rm. {William Robotham - Chief Engineer} c.c. Rm {William Robotham - Chief Engineer} /GWH. {George W. Hancock - Head Chateauroux} 6. B. IV. In our memo of the 16th inst., re Sparking Plugs, we stated that the terminal was further from the inlet pipe on the Champion L.10 than the LB.9 plugs. This is not correct. There is nothing to choose between the two in this respect. The nearest point is the bottom of the inlet pipe flanges. We shall be continuing our running on this car with five A.C. Plugs N° X.428, and the one Champion L.10, which has already run 4570 miles, as the K.L.G. plugs have been returned to you. --------- Rm {William Robotham - Chief Engineer} /GWH {George W.
