MTO: Southern France, Italy, N. Africa, Malta, Corsica. 43-45 RAF/RCAF and USAAF.
The 31st FG USAAF I think was the last US unit to operate it in the MED, before they transitioned to P-51s (1944).
It never served in NW Europe as the IXs (and others) were ear marked for there, it was a logistical call to send the VIIIs "overseas", where the slightly longer range and tropical filters were deemed as needed more than in Europe.
