| X7655 Sg.{Arthur F. Sidgreaves - MD} from EFC. EFC2/AD3.6.29. 22-EX STARTER FAILURE. Answering your Sg{Arthur F. Sidgreaves - MD}9/El.6.29, it is arranged to be the case on production, that no ebonite parts whatever will be used in connection with electrical equipment. Certain ebonite parts however, are still in existance on some of the experimental S.S. cars. These will be replaced by bakelite mouldings as the moulds become available. In the meanwhile further disaster, is, we have reason to believe, very improbable. EFC. | ||
