My father served in the Royal Marines in World War II. He took part in the invasion of Sicily and mainland Italy. Whilst in Italy rumours circulated about one of Mussolini's hats having 'gone missing' during the allied advance. It was believed to have been in the posession of partisans and later in the possession of a member of the British armed forces. The story was reported in the Eighth Army News. My father returned from the war with the hat (see picture) and a copy of the Eighth Army News. He resisted attempts by officers to take the hat from him. He always believed it to be Mussolini's hat. IWM have seen photographs and so far have not been able to confirm its origins.It is certainly made in Sicily before or during WWII. An expert could verify its identity.
