Cross in the Bentley Frame. Now that we have the isolated change speed lever the necessity for a separate gearbox on the Bentley disappears, unless you consider it to be essential in order to get a suitable cross in the frame. In view of the fact that all the Americans succeed in getting a cross in their frames with their universal gearbox and engine construction, we should like to know if it is not possible to get satisfactory construction on these lines with the Bentley when the engine is pushed 3" forward. Actually with the separate gearbox the cross becomes very short and has to leave one or other member of the main frame severely alone. We feel that while the design of the Wraith is somewhat static owing to our work on the SpectreCodename for Phantom III, it would be a good opportunity to get the Bentley cleaned up because on this car there is a straightforward issue without the complication of independent wheel springing.
