Hurricane Rotol mixture controls?

I haven't found anything in the Pilots Notes that talks about gradual adjustment of Mixture, just fully back (Rich) or fully forward (Lean)

In the ferry pilots notes it states;

Mixture. Mixture is either Automatic Rich or Automatic Weak. The lever friction is adjusted by a knob concentric with the throttle friction control.
The throttle and mixture controls are interconnected and in some cases it will not be possible to bring the throttle back below +2 boost without moving the mixture control. In these aircraft no harm will result by moving the mixture lever back with the throttle until zero boost is obtained.
In some of the latest aircraft mixture control is fully automatic and there is either no lever or if one is fitted it is wired in WEAK.
