No such mention of this wiggle room is mentioned in the Hurricane I manuals though. Here is an excerpt describing its operation from the Spit I pilots notes:

I think that assumption is incorrect Blackdog Kt The Spit manual implies that its just a matter of using the Prop pitch control as a Vernier device that enables you some additional control of Prop pitch other than just the Coarse and Fine stops. The location of the Prop pitch control in the Spit I makes it a little easier to manage.

That’s very interesting information IvanK, thanks for sharing!

Regarding the de Havilland two position propeller on the Spitfire I: "If the two position control is fitted on this aeroplane it can also be operated to give various airscrew pitch settings between fine and coarse; this is obtained by slowly moving the control between its range of movement until the desired r.p.m. are obtained. […] This in effect will give a similar improvement in performance to that obtained by means of a constant speed airscrew."

Are the devs aware of this?

Hmm, come to that; are the devs aware that Spitfire Is were equipped with constant speed propellers during the Battle of Britain?
