Hoping to add to list knowledge I've done a modest photo exhibit on 3 Huret Jubilee rear derailleurs and 2 Huret dropouts. This is in response to recent exchanges about fitting these derailleurs.
Profiled:
Jubilee from 73 Raleigh Competition with Huret DO Jubilee from c.74 Motobecane with Campagnolo DO Newer Jubilee with holes in pully cage, unknown what it fits, maybe one that requires an adaptor.
The photo exhibit is on wooljersey (thanks again and again Morgan!). You may have to double click twice on an image to see enough detail.
