| To E.{Mr Elliott - Chief Engineer} from EFC. EFC4/T20.9.18. X.3362 - LIGHTING INSTALLATION AT W.W. Further to our note EFC1/AT18.9.18, we now find that the electrician has in stock, some simpler kind of Simplex tubing of the slip-in type without any threads, which I think is the kind you originally had in mind. This will make a simpler job than the screw threads and you may be able to cut lengths of these down there. We are hoping to find sufficient of this type for the purpose. EFC. | ||
