Well, the tool you pictured looks like an amalgam of Campy and Mavic parts. Here's a page showing the Mavic cutter:
The text describes it as "adaptable to Italian tool holders" by which it likely means "Campagnolo."
You can see that it bears little resemblance to the Campagnolo #725 bottom bracket facing mill:
But it does strongly resemble the cutter in your original picture.
