I have managed to have a look at the photo you quoted since (after some research) I discovered to have already received it by e-mail on September 1999 by someone pointing at me that very caption!

I am thus able to confirm that it has nothing to do with NSGr.7, being part of a series still present at the Bundesarchiv and showing a rare twin-place Fiat G.50 in German markings while refueled.

That version was meant only for training but in this case it was employed as a liaison aircraft by the Luftwaffe and the plane is painted in Italian Verde Oliva Scuro 2 uppersurfaces with Grigio Azzurro Chiaro 1 undersurfaces. The photo was presumably taken in late 1943/early 1944 and the personnel shown was probably Italian too (the photo I've in my Mac is too little to discern the badge on the cap), which would imply it was taken in Italy.

Hope to have been of some help.
