| - 2 - EXPERIMENTAL BY/WERG/EF13. 12. 21 (Contd') D.50549D.C. Dynamo End Bracket Pinion End (1 print). D.50550 Retaining Nut (1 print). D.50538 Retaining Nut for End Cover (1 print) The quantity of D.50239 and D.50305 has been increased to 16 off each, and also it should be noted that D.50243/4 called for in our memo BY/WERG/EF16. 9. 21 are no longer required. Commutator - Section 8090. This section to L.O.P. D.50447 was instructed in our memo BY/WER2/EF24. 10. 21. Frame and Field Winding - Section 8100. The complete details of this section will be issued in the course of a day or so. This will then complete the instructions for the Dy{F R Danby} nemo. It should be noted that it is proposed that this design of Dynamo will be used on chassis with or without magneto, the shaft extension at the commutator end when not in use being protected by a sleeve fitting on to the tapered portion of the Armature Shaft.
