As part of a small parts lot, I recently acquired this Huret Jubilee rear derailleur:



What derailleur hangers will it work with? I ask mostly because I just saw this eBay auction for a reproduction adapter which allows it to connect to Campy, SunTour, and Shimano hangers:



Is the derailleur Huret-only out of the box? Will it work with a Simplex hanger as one would find on a PX-10?
