| To RHC.{R. H. Coverley - Production Engineer} from EFC. X8692 EFC5/T10.11.27. CONTACT BREAKER TO LEC.2460. Further to our EFC7/T7.11.27, will you kindly note that the gauge of the contact point arms should be .064", similar to the one which you made up for us to test. We have noted, however, that there is another gauge specified as an alternative, viz. .080", and we are handing you herewith the contact breaker which ran on the test, so that you can re-arrange this for further test with .080" contact point arm, which we should like to have as soon as possible.
