| To R. {Sir Henry Royce} from Ck. {Mr Clark} c. to CJ. c. to E. {Mr Elliott - Chief Engineer} c. to Wor. {Arthur Wormald - General Works Manager} c. to Bn. {W.O. Bentley / Mr Barrington} c. to By. {R.W. Bailey - Chief Engineer} c. to Ds. c. to EP. {G. Eric Platford - Chief Quality Engineer} c. to PN. {Mr Northey} c. to Hs. {Lord Ernest Hives - Chair} X.3014 - LUCAS E.575 DYNAMO. X.295. - SMITH (T & M) TYPE A DYNAMO. Further to our Ck {Mr Clark} 2/T4.3.20, we attach further comparative out-put speed curves of the Lucas and Smith dynamos. These were sent to you under cover of our EFC {E. Fowler Clarke - Electrical Engineer} 4/T12.5.19 and show, besides the comparative cutting in speed, the comparative rates of the rise of current both hot and cold. We attach copies of these curves also to Wor {Arthur Wormald - General Works Manager} 's and PN {Mr Northey} 's copies of this note as these were not sent to them at the time. Ck. {Mr Clark} | ||
