Hi Bob, the derailleur won't work right out out the box on those Huret dropout. I remember when John was working on my Sports Tourer and I wanted to use a NR RD. He brazed on some extra brass onto the hanger then filed it down to extend the stop further back. Otherwise I thought there was a tabbed washer adapter that allowed for Campy derailleurs on Huret dropouts. I remember this suggestion came up when I was asking for suggestions on other parts to make.
