| -2- in which case we shall standardise this on all our cars as soon as we have carried out the necessary tests on it. We have recently carried out comparative tests between Gallay and Marston matrix blocks. These were checked very carefully and the results are shown on attached sheets of curves. Sheets 1, 2, and 3 are respectively results of tests carried out by Messrs. John Marston Ltd., Messrs Clayton Dewandre and the Harrison Radiator Corporation of U.S.A. and when compared give a check on the accuracy of test. Further the Gallay matrices weighed considerably more for the same cooling than the Marston cores while the Gallay prices were definitely higher than Marstons. In view of this we do not think that the Gallay is as good a proposition as the Marston core. We would mention that we get no leakages or structured failures whatever with the Mk.V or Mk.VI radiator blocks. We would also mention that a Mk.VI radiator block of 473 sq/in. frontal area and 2.000" deep, weighing 25 lbs. provides more than adequate cooling for our Bentley car.
