Well, the general public, still have the "Five reverse & one forward gear" attitude towards Italian tanks. The "8 million bayonets", certainly had many members, who were less than enthusiastic when it came to fighting for Mussolini.
The Regia Aeronautica's activity in the Battle of Britain, was very limited, contributing 5% of the aircraft, they flew few sorties, the first on 24th October 1940, raiding Harwich & Felixstowe, the last major raid, on 11th November, with smaller numbers engaged in attacks later in November.
They lost 10 planes in combat (the CR42 Falco in the RAF Museum, being one) & a similar number in accidents.
