Does anyone have more information on this topic?
I found this:

Surprising that such machines were used as transport in the evacuation of the Crimea in 4'44.
At least some of the info given there is strange as Luftflotte 2 was not on the Eastern Front.
Additionally I found that:
Transp.Fl.Staffel 5 had 8 "Piaggio" in 1'44, 3 of them "new from factory".
Anyway: Who knows more? I am curious!
