Look at the pictures
The first is the pilot's Badge of Regia Aeronautica (before 8th Sept 1943);
the second is the badge of Aeronautica Nazionale Repubblicana,without crown 'cause Repubblica di Salò was a "Republic" and not a monarchy.The 3rd shows the badge of the pilots of South Italy,flying with the Allies, with the English crown (and without fasci evidently)
