| X2894 W/N. To A.{Mr Adams} from EFC. EFC6/AD20.5.30. X.2894. TUNGSTEN CONTACT POINTS. We thank you for your A17/H15.5.30 and note your remarks. In regard to the tungsten points however, it is really the frequency of necessity of ordinary running replacements in which we are interested. We should be pleased if you could give us information a little more in detail as to why the replacement is necessary and as to what number of miles you find, from observation, tungsten points will satisfactorily run the engine without needing attention.
