If memory serves me correctly, the degree angle of the mounting bracket for Huret derailleur dropouts differed from Campy dropouts. This affected the Campy derailleur from working properly because it was over-extended.
I vaguely recall what you describe, but when I worked at a Raleigh dealership in the 1970s, often a "hanger bracket" would instead be applied to the derailleur to adapt it. The solution was not pretty, but it was functional.
