German bomber units in Italy September 1943

[Guaido]

I am researching the fightings between German paratroopers (II./FJR 6) and Italian units at Monterotondo, close to Rome, on Septemebr 9th and 10th, 1943.

Italian reports state that German bombers attacked the Italian positions in the evening of September 9th and in the night between September 9th and 10th, the italian AA Group also claims that some bombers were shot down.
I checked the lists of "Flugzeugunfälle und Verluste bei den Verbänden" for the months September, October and November 1943: I found the confirmation of one Ju.52 shot down, but no confirmation about any bomber. Fact is, that such lists are not complete, as sometimes the details of losses were noted weeks or even months later.

My questions: Which were the German bomber units in Italy ion that period? Any after actions report known, where the actions on Monterotondo were noticed?

Thanks in advance for any help!
