I attach a photo of the D520 coded 20, included in the Regia Aeronautica; the lower part of the nose appears in light grey in this b/w photo, with sharped edge; What is the color? Why the Italians would not have applied the disposition to flight over the French territory, with the risk to to be recognized by the Germans?
Ciao
