Flashman, here in Italy we have a strange situation.
The fasces is a simbol that cannot be used. Fascist party and all its symbols and ideologies are strictly forbidden by our constitution. However, hammer and sickel are used without problem.
I agree with you that Hitler dictatorship and Stalin regime were both evil government, but as you said History is written by winners.
However, after my preceding wrong observation I have made some investigation about Italian symbol.
Forst roundel ever used by Italy as military mark for aircrafts was in first world war, a roundel red outside, and green inside, used on fighter wings. It was changed in 1918 as green outside and red inside. It was changed again in 1936, becoming the roundel with three fasces inside. Up to 1943 it was used by aircrafts. The Navy and the Army, used as mark the banner with the Savoia red shield (the one on the left in the Black_Elk pictures may be suitable).
After 1943 the Salò Republic, the norhern part of Italy that continued to fought with Germany, used a three colored banner with an Eagle in the center.
After the war the roundel selected for military marking is red outside and green inside. The justification is that if you take the Italian banner and wrap it around the pole you will have a cilinder red outside, green inside with white in the middle.
