Gentlemen -
You may be interested in the photos of Polikarpov I-16s which were captured intact by the Germans during Barbarossa posted on the Luftwaffe Experten Message Board:

These either still carry the Russian markings or provisional, field applied Swaztika. I have not yet seen a single seat I-16 in full Luftwaffe markings.
There are also several photos of the two seater trainer version of the I-16 designated the UTI-4 on LEMB:
