Here is T6+AN, a plane shown in several frames from an Italian newsreel taken in September 1941. The red "A" and "N" indicate that it belonged to 5./St.G 2. Together with T6+DP, it would seem to be the only plane to have been decorated in such a remarkable fashion.
In this frame, one sees a bit more of the snake.
Since the camouflage scheme is not discernible, I've used the splinter pattern of T6+DP.
T6+AN is available
here.
