The photo in the link I posted and that shows 932569 may have been very well taken at Wunstorf. Not all those images are from the Gatow dump. So your report might be pretty much correct when stating that this a/c was found at Wunstorf.
These "<<II" markings the reports mentions are another thing, though. In the recently published "LO+ST" photo book by Hideki Noro there is another photograph of what seems to be the 932569, showing the starboard side (page 33). But no staff markings are visible here either.
MAYBE this photo also shows 932569 (the Fw190 to the right of the Ju88G):

IF that's true, then I still can't see any markings. So either the report is wrong here, or those staff markings were applied in any non-standard way (very small? yellow on light gray?) or in some place not visible in those images (engine cowling?)
In volume two of Jerry Crandalls book on the Fw190D the wrecked Dora visible to the right in the large photo will be featured. So maybe we will also get a peek at this Fw190F standing next to it..
Hope that helped a little, maybe others can tell you more.
Cheers,
