In fact, years ago, the standard fix for chronic broken axles was to use a Campy replacement axle.
One of the six speeds I broke was a Maillard. One the five speeds a Normandy. The other five speed was on a 73 Schwinn Super Sport, no idea on the hub brand though it did have a Sun Tour freewheel. I don't recall what the other six speed was.
