| EFC2/T30.6.26. -3- Contd. Two recent tests we have made have shewn that U.S. tungsten points on U.S. contact breaker, but for the rest with our exact and complete standard chassis ignition, including coils, condenser, etc., behave as well as they do on U.S. equipment, and one corresponding exchange test has shewn that Remy equipment with much smaller current has not done too well on our standard platinum points. Therefore, from the tests we have made we are nearly sure that it is wholly a question of material, and that we are not getting the same tungsten material here as you get. It is naturally rather difficult to obtain U.S. stuff from the agencies here, because they know we have no idea of using their standard equipment, but merely want to make tests, and they are inclined, as I suppose is natural, to be rather awkward. What we are particularly wanting at the moment, therefore, is as previously stated, so that we can finally prove the point and also have analyses made, as Messrs. Johnson Matthey have recently offered to do for us, of the English supplied tungsten as compared with the U.S. material. EFC. | ||
