I'm sorry, it's computer mayhem here currently, so OH.
The clues were your "Italy somewhere" comment, plus I42's "are they Ju 52's?" question, which got me thinking about the Luftwaffe's airlift to Tunisia in late 1942.
The airfield has changed greatly now, although some blast pen walls remain visible on GE. Those odd turning circles on the runway (faintly visible in the original photos and confirming my suspicions as to the location) remain.
