I believe there was a long-cage version of the Cyclone that should handle 32T. Also the SunTour VGT Luxe would definitely handle 32T and might be a little more sturdy than the Cyclone, though not quite as pretty. I also really like the Campy Rally, on topic, but I don't know if it was available in 1978. I like the Rally better than the Huret Duopar. The Shimano Crane GS also wasn't bad, pretty sturdy and well finished, though it probably didn't shift as slick as the SunTours or the Rally. FWIW, I'm currently building up an early 80's Assenmacher randonneur for my wife to match one I ride. Mine has Campy Rally, but I'm leaning toward the SunTour VGT Luxe for hers.

Must be able to shift to a 32 tooth cog and handle chain length of a triple. Or are there good trouring ders that only shift onto a 30? One of my favorites is the SunTour Cyclone, but it only shifts to a 28 tooth cog so I don't think of it as a real touring der--despite the fact that it could easily be used with low gears with a small granny in front, indeed as many racing oriented ders have been.
