Hello Ludovigo, I did not know that the 91 Sq. war diaries are still around today.
From the books and articles I have read, I always thought that they were lost before and during the 8th of September armistice.
I understand that Gregory Alegi is also a very good historian on Italian Aviation.
Maybe, you might want to try and get a hold of him, or perhaps even Nicola Malizia.
Good luck with your research,
Vinman.
