| 6110 To Rm.{William Robotham - Chief Engineer} WST BY/RD.9/B.3.2.37. FERRULES FOR IGNITION WIRES. As a result of our enquiries, the most economical method of producing Ferrules, has proved to be production from from Erinoid rod, with engraving similar to the samples attached hereto. We use Erinoid at present on the low tension cable ferrules, and this material has given us every satisfaction. Will you please say if you see no objection to the engraved figures and letters as compared with the moulded figures and letters used at present. If you agree, we see no reason why this should not be adopted on production as soon as convenient, without scrap. fitted to 36 EX & recorded. RH{R. Hollingworth} 5/2/37 BY/RD. | ||
