I am not sure I understand this thread, but I am aware of a Campy large flange rear track hub that was constructed differently for a narrower Cinelli track bike. Some Cinellis have 110mm rear-ends, and you can't make a normal Campy track hub fit without removing the toothed washers from the assembly- and even then it will be too wide.
I don't understand why you would necessarily need a narrower spindle. Can't you simply cut it shorter and grind smooth?

Dennis Young Said: I'm in need of a rear 110 mm track spindle for a older style campy track hub. Harris cyclery carries them, but they are now only sold in front and rear sets. The spindles come with everything that screws on it, including the outer track nuts. Anyone need a 100mm front track hub spindle set? A little pricey perhaps, full sets run 59.95. Alternative suggestions also appreciated.
