This skin is an adoption of "II/SG 4 by Jawzzy" Which was based on some pretty inaccurate reference.
Fw 190F-8 of III/SG 4 in June 1944 while based in France. Pilot unknown. The use of blue on the side number and Gruppe ID bar is speculation based on the fact that they are a lighter color than the yellow under the nose in the reference photo. Blue is usually reserved for the Gruppe command flight and the use of "0" also is rare to see in the line squadrons, so these elements fit logically for a plane in the Gruppen Stab. Camouflage is the standard RLM 74 and 75 grays. Yellow IFF marking are on the lower cowl and rudder.
