Well it looks like Constanza and Varna/Sevastapol. Not sure how they came into play in Stalingrad.

As far as the Regia Aeronautica, I looked here:

61st Gruppo appears to have operated Ca-311.
21st Gruppo had MC200/MC202
71st Gruppo with BR-20M, Ca-311, Ca-312, Ca-164.

Can't find any mention of a Cant Z in Russia.

I'm puzzled with those seaplanes as well. Need to check in Bergstrom's book.

Cant Z was mentioned in some "second hand" sources without reference to documents. (I've done quick search, but didn't bookmark or copy). So might be a mistake and can be ignored.
