| Wd.{Mr Wood/Mr Whitehead} from EFC. X4383 EFC6/T7.10.21. X.4383 - BRUSHES FOR R.R. GOSHAWK DYNAMO. X4383 Further to our EFC4/T10.9.21 requesting you to order up brushes for the R.R. Goshawk dynamo from the Morgan Crucible Co. and Le Carbone Co., I have a note from Mr. Royce to the effect that we should order Le Carbone's grade O quality brushes which have been proved by Messrs. Royce Ltd. to be distinctly superior to those supplied by the Morgan Crucible Company. Would you, therefore, order up from the Le Carbone Co., in addition to those already ordered, two sets (8 brushes in their "O" quality to print D.50301. The terminal D.50302 will be produced by us and therefore the pigtail as supplied should be without this piece as before. EFC. Rec'd | ||
