| X.3513. To Wd.{Mr Wood/Mr Whitehead} from EFC. EFC3/T14.7.21. X.3513 - SAMPLE BAKELITE INSULATION FOR EXPERIMENTAL PURPOSES. Answering your Wd{Mr Wood/Mr Whitehead}2/NJ11.7.21, these insulations are required for various pieces, e.g. small plates, bushes, etc. on our ballast resistance, actuator box, and main switch. The Micanite & Insulators Co. Ltd., should therefore be asked if they can supply two pieces each of the equivalent material in "Paxolin" to grade XX Bakelite dilecto (paper base) and grade A Bakelite Dilecto (asbestos paper base) all of dimensions 1/16" x 6" x 6" and also two pieces 1/8" x 6" x 6" of similar material to Continental Fibre (cotton Duck base).
