The bodywork appears to be an attempt at a wedge shape, which became fashionable towards the 1969/71 period. I've checked the race entries for Italian F3 for that era, and there's nothing Renault powered. Earlier years had works Alpines, and the French BEP cars, but I can't imagine why an Italian constructor would use a Renault engine when it was clearly uncompetitive.
Was it ever raced?
