Post some pics of the stampings
Old school OZ Racing wheels can also be stamped "ruote oz"
They look a lot like Fittipaldi 5 stars (looking where the red type is stamped on the spoke) and Fittipaldi is a sub-brand of OZ racing.
Actually, look at where the Fittipaldi logo is compared to the center cap screw hole compared to the valve stem... I see they are exactly the same as yours, even with the bad pic
