"I SORCI VERDI" squadron Italian Air Force badge

Beautiful pin badge of the Royal Air Force Squadron the "I SORCI VERDI"

From Wikipedia:

The 205th "Sorci Verdi" bombing squadron was a squadron of the Regia Aeronautica 
belonging to the 41st BT Group (land bombing) of the 12th Wing framed in the III Air Squadron.

All the planes of this squadron carried three green mice, standing on their hind limbs, drawn 
on the fuselage, above the white line that ran around the plane, right in front of the tailgate.

The 205th was the first of the Italian squadrons to receive the three-engined SIAI S.79 in 
October 1936. The "Sparrowhawk", thus the aircraft had been nicknamed by the General Staff 
of the Regia Aeronautica (the nicknames of the aircraft were in fact indicated and adopted 
only with official directives), it was an aircraft adapted to the role of bomber having actually
 been born as a postal transport (see Ali d'Italia n. 9 "SIAI S. 79 - 1ª Part" / Cesare Gori 
(Turin: La Bancarella Aeronautica , 1998)

There is no agreement on the origin of one of the best-known departmental badges of the
 Italian Air Force. Three mice standing upright on their hind legs, cheerful expressions,
 two of which are intent on conversing. The most valid thesis traces the origin of the symbol 
back to the Spanish Civil War. In March 1937, second lieutenant Aurelio Pozzi would have drawn
 the three mice after hearing a non-commissioned officer exclaim in Roman dialect:
 "Tomorrow we annamo about Barcellona and je famo sees them green mice", meaning causing an extreme fright.

The following 7 September, General Valle orders with a special note that:

"The Green Sorci badge [with the three rats in an upright position] marking the aircraft that
 participated in the Istres-Damascus-Paris international air competition is to be adopted as
 the official badge of the 12th Stormo B.T."

And the name became famous when the squadron with Colonel Biseo and Captain Bruno Mussolini 
took the first three places in the Istres-Damascus race in August 1937, and even more so after 
the Guidonia-Dakar-Rio de Janeiro flight in January 1938.
