Chas's pic with the 3 pink circles is about Jubilee, is that what you plan to use? Any Jubilee can be mounted on a Campy-style dropout, but only the one on the Left can do it without an extra washer. The extra washer is small and unobtrusive, it's not like using a mounting "claw". The thickness of the washer does require you to use a slightly longer mounting bolt, so the one meant for Huret dropouts likely has too short a bolt.

I can supply the washer you need, if you end up getting a Jubilee that's not "natively" built for a Campy hanger. In my limited experience, the native-Campy style are more rare; most Jubilees you'll find are one of the two other styles, natively Huret, needing an adapter washer
