I think you're probably right Chris, and good reasoning! The civilian clothing, and the facial features, look more Italian than northern Europe, I'll admit.
How about this for a thought. South West coast of England, specifically South Devon prior to the invasion. That whole area was boxed off in preparation to the Normandy landings. My reasoning is that the buildings look similar to that part of Devon and the men standing round in cloth hats and ties. Alternatively, it could be Normandy following the invasion.
