| Remarks on the running - general X5894 To Wd.{Mr Wood/Mr Whitehead} from EFC. c. HY.{Tom Haldenby - Plant Engineer} EFC3/T5.3.27. PLATINUM CONTACT POINTS. In view of the near future possibility of standardising tungsten points - we hope to do this after the completion of the impending 20 HP. 10,000 mile test - we suggest that you should not order any further stock of platinum points without first communicating with this Department.
