At the RPM the spinner would be turning, the spiral should be a blur.

Some infos about the spinners of Bf 109 G, found in "Camouflages and Markings of the Aeronautica Nazionale Repubblicana" by Ferdinando D'Amico and Gabriele Valentini (these infos are the same for Luftwaffe Bf 109s):

 

1) Spinners and propeller assemblies were painted by sub-contractors in RLM 70.

2) Spinners and propellers were fitted to the finished aircraft on the assembly line and painted there with the one-third white segment.

3) After leaving the assembly line, aircraft were taken to a Fliegerhorst (aerodrome) where acceptance flights were made, then moved to an Abstellplatz and from there to a Luftpark. During one of these phases, probably either the Abstellplatz or the Luftplatz, the spirals were added to the already finished aircraft spinners, overpainting the scheme with the white segment (as confirmed by the presence of the former scheme, often still visible on the spinner's backplate disc).

 

However, IMHO, in the time range of "Il-2 Battle of Stalingrad", on F-4 and G-2, this spiral (Spiralschnauze) was not yet in use. Spinners were generally RLM 70 "blackgreen" with one-third white segment, the tip being sometimes painted in the Staffel color. On winter camouflaged aircraft, they were very often overpainted in white, more or less carefully.
