| WJ83 To EP. {G. Eric Platford - Chief Quality Engineer} for Mr. Wyer. from EFC. {E. Fowler Clarke - Electrical Engineer} EFC {E. Fowler Clarke - Electrical Engineer} 2/T26.10.23. X.4383 - GOSHAWKAero EngineCodename for 20HP Car / Aero Engine after KestrelAero Engine DYNAMOS. We have received from you dynamo No.604 which you say is noisy. In return for this we shall be letting you have dynamo G which though marked with an experimental letter has had no experimental work done upon it, and has only run a comparatively short distance on 5GII on the road. It is sent to you in an up-to-date condition, i.e. commutator specially undercut by the new process and brushes bevelled off, and passed by us for production. The machine will be sent to you shortly.
