Burt - Engineer} has written to Hd.{Mr Hayward/Mr Huddy} recommending increasing the load on the torque re-action dampers. The suggestion that the throttle pedal can be used to alter the ignition in France to improve slow running should be investigated. [Handwritten: Advance] WRAITH. (1) Are all the latest oil holes to improve lubrication on the Wraith III crankshaft ? [Handwritten: to report] (2) Expt. Dept. to issue a report saying whether the Wraith silencer suspension is what we want on the Bentley. [Handwritten: Refer over to E - Rm{William Robotham - Chief Engineer}/wym.{G.

[Handwritten: over to] (1) It was decided to fit propeller shaft dampers on all 4 1/4 litre Bentleys (555 Bentleys and 350 25/30 left the Works without a propeller shaft damper). (2) Instructions should be issued to Depots to check over any other points likely to cause clutch judder when fitting propeller shaft dampers.
