[Handwritten Annotation: ALL HAVE (struck through) NO BAFFLE, EXCEPT B 91 CW] Bentley Piston Failures. Can you please let us have the chassis numbers of cars on which there have been piston failures ? We want to find out whether in all cases failures have been on cars that have not got a baffle in the lower half to prevent loss of oil pressure when braking.
