Note: This is a copypaste merging those four Caproni models:
Caproni Ca.101 Italy, Hungary & Nationalist Spain*:
*The picture showing a Ca.101 in (rather odd) nationalist markings appeared in Purnell's 'Bombers, 1919-1939'. Actually no any information about Ca.101's in Nationalists Air Force. Probably this profile is fiction.
Caproni Ca.111: Italy, Peru and Nationalist China:
Note: The colours of the Chinese version are uncertain.
Caproni Ca.133: Italy (Plus ala Littoria), Co-Belligerent Italy, Austria, Germany & Great Britain:
Caproni Ca.148 for Switzerland and Italy (Ala Littoria and Aerotrasporti S.A.)
