| Contd. -2- EFC {E. Fowler Clarke - Electrical Engineer} /T30.4.23. the matter of brush material tests can, as far as we can see at present, be considered complete, and the dynamo test corner will then be available for various tests on the vibrator regulator control of various machines. The necessary tests on the E.A.C. dynamo will take place at the appropriate time. In the meanwhile the pre-arranged series of brush tests on the GoshawkAero EngineCodename for 20HP Car / Aero Engine after KestrelAero Engine dynamo will be taking place on the continuous running rig.
