Coverley - Production Engineer} Hs{Lord Ernest Hives - Chair}/OWH. E.4/HP.9.9.33. re Bentley Exhaust System. It is important in connection with the flexibly mounted exhaust system on the Bentley that the castellated nuts securing the brackets to the silencer and the castellated nuts securing the flexible link to the tail pipe should be backed half a turn after tightening up, so that the requisite degree of freedom is provided for the silencer to expand.
