Childs}1/SW. 22.8.40. we should like to know from Rm{William Robotham - Chief Engineer}/CTS{C. Trot Salt - Carburation} whether the test bed results confirm that KLG. FE. 30 X. plugs were responsible for the running after switching off. We are prepared to run Lodge 741 plugs in 9.B.V. (Signature) Rm{William Robotham - Chief Engineer} | ||
