Sidgreaves - MD} From Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} c. to Wor.{Arthur Wormald - General Works Manager} c. to Db.{Donald Bastow - Suspensions} c. to Bn.{W.O. Bentley / Mr Barrington} c. to EP.{G. Eric Platford - Chief Quality Engineer} c. to MX.{John H Maddocks - Chief Proving Officer} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}2/KW.2.10.34. Front Wheel Tramp upon Brake Application. We now have Mr. Fairey's car at Derby. We understand that Flight Lt. Staniland was unable to reproduce this high speed tramp in the presence of Lp.{Mr Lappin} and Bn.{W.O. Bentley / Mr Barrington} The car was subsequently driven to Derby by Hs.{Lord Ernest Hives - Chair}, who intentionally put up as high an average as possible and endeavoured to reproduce the trouble but failed to do so. Since the car has been at Derby we have been unable to make it tramp. We agree that it is particularly bad for wing movement and is therefore particularly useful to us for experimenting with this trouble. In view of EP{G. Eric Platford - Chief Quality Engineer}'s note re Mr. Tippe of Belgium we should like to emphasize that we have not yet had an example of this trouble demonstrated to us.
