Looks like Ruspa,Mille Miglia or perhaps Amadori.
Being so wide they will be at least 1970's onwards.I do not think earlier.
If it hasnt got 'ABARTH' cast into it......then maybe they are not Abarth.I do not think they are Abarth but i will not say 100%.
There are many wheels with Abarth cast into them (124,131,127,campagnolo,cromodora,speedline,open top race cars etc etc).
There will be a manufacturors stamp somewhere on them and most likely a year code.
Check thoroughly for cracks,this is the best reason to buy newer replica wheels.
