| X4054 To EP.{G. Eric Platford - Chief Quality Engineer} from EFC. c. By.{R.W. Bailey - Chief Engineer} EFC3/T4.1.24. X.4054 - CONDENSER FOR 40/50 BATTERY IGNITION WITH FLEXIBLE CONNECTION. x44236 Referring to our conversation on the above subject, please have turned up my note EFC3/T8.6.23 addressed to By, copy to you. We, as the Elec. Expl. Dept.. now definitely recommend that in the case of replacements and repairs, both the flexible earthing connection and the larger capacity condenser should be used. In the case of the flexible earthing connection we have all along advocated this and we again repeat that we do not consider the 40/50 ignition job correct without it. This is from our own experience on electrical matters. In the case of the flexible earthing connection there is a standardisation sheet, which takes the matter out of the hands of the Expl. Dept.
