Books, articles or other sources for Italian Airacobras?

[Kari Lumppio]

Hello!

Besides Mattioli's Bell P-39 Airacobra in Italian Service? It'a good book but identifies the German units targeted by the planes better than the Airacobra units, pilots or planes. It may be because of the source material available when written, of course.

For example I would like to know more about unit markings and insignia. I have not been able to sort them out for the Co-belligerent (Balkan Air Force) period.

Cheers,
Kari
