For the first Bentley lll we have provided speedometer gears in the box itself, the servo shaft tunnel being closed by a cover. If it is desired to try a hand control on the rear dampers, it will be necessary to provide an adaptation of the present standard damper governor unit to the universal gear box. Normally the unit itself would be modified, but as this gear box will be used only on the first car, we propose to adapt the existing control unit by turning it at right angles to the servo drive shaft, so as to avoid the frame cross. The adaptor bracket is shewn on G.CD.277, herewith, with the necessary gears. The upper gear provides a speedometer drive, which will not be required and need not be detailed. It would only be used if it was decided to make a number of these universal gear boxes, in which case the pair of speedometer gears now in the box would be deleted. The adaptor pattern should be made as economically as possible. The adaption of the control, which will also be only applicable to the first car, will follow on another scheme.
