| EFC c-By.{R.W. Bailey - Chief Engineer} from Mx.{John H Maddocks - Chief Proving Officer} X5661 Mx{John H Maddocks - Chief Proving Officer}3/T29.12.26 [Stamp: RECEIVED Hs{Lord Ernest Hives - Chair} 29 DEC 1926] 20-HP.Chassis - Dynamo. No.161. (Carcase) Memo reference EFC3/T16.12.26. We have tested the above machine which is fitted with an Experimental Armature on 4 different chassis, and have run each chassis approximately 50 miles. We have found the Dynamo very good indeed for silence, and I feel sure it will be a great advantage if the tests can be pushed forward, so that the alteration can be introduced as soon as possible.
