Herewith the following scheme :- F.CH.103 Modified Steering Column Controls. This scheme is necessary owing to the elimination of the ignition control. Please note that the centre portion of the quadrant may be affected by the design of the horn switch, so that it should not be detailed until the switch design is received. The movement of the Riding Control Lever has been reduced by 9° to 81°, and one of the control levers is to be modified in length to compensate for this reduction.
