| X.2894 To RHC.{R. H. Coverley - Production Engineer} from EFC. c. Hs.{Lord Ernest Hives - Chair} E.{Mr Elliott - Chief Engineer} Da.{Bernard Day - Chassis Design} EFC4/T16.8.20. X. 2894 - RE TUNGSTEN POINTS. Mr. Royce is still not satisfied that we have tried tungsten points sufficiently, but now wishes that we test some of exactly the same make as the Delco Company and that to be sure of this, we should remove some from the Delco ignition and use these actual points. We are therefore handing over to you an old Liberty contact breaker upon which you will find three pairs of points. Will you kindly have these three pairs of points removed and fitted to three sets of standard R.R. chassis blade and screw for further trials on cars. It would seem that we cannot be sure that tungsten points are really unsatisfactory until this has been done. 27 / 22.9.20 1 set fitted to H.E.X. 1 set on test. 1 set in hands of R.H.C. EFC. | ||
