E/HDY.{William Hardy}2/HP.19.3.37. Wraith III Governor Control Unit for Dampers. The Operation Planning Department have made suggestions to us for reducing the cost of the pump suction filter on this unit and this raises the question whether the filter is required at all in view of the fact that, although there is a place for it on the 25/30 and Bentley units, it is not fitted on these cars but is only fitted to the Phantom III. We should like to know whether the apparent inconsistency which at present obtains can be cleared up by a decision either to delete the filter altogether or to fit it to all cars. Failing this, can we assume that it will not be required on the Wraith?. [Handwritten] Lus what about this GMy E/HDY.{William Hardy} Hdy{William Hardy} | ||
