I wonder if anyone knows details about the combat history of this plane (Polikarpov I-16 type 10 with yellow spinner and tactical number 71):

The book
Polikarpov I-15, 1-16 and I-153 Aces claims that the plane was flown by Soviet pilots in summer of 1938 in the defense of Hankow (Wuhan).
In other places it has been stated that the plane had this camo and markings in 1939 and that it may have been shot down in air combat (place and location unknown).
