| X. 4333. To EFC. BY/RD/MLJ 17.11.23. X.4333 - 20 H.P. DYNAMO BRUSH GEAR. Replying to your EFC3/T16.11.23, nothing has been done in this matter so far. I would point out however, that all the Brushes for the present programme are delivered, also if the slot is increased to clear the spring why have a slot at all? We could have the top of the brush sloped and no slot. BY/RD. | ||
