On the colbolto ones the slots that take the brake shoes are more rounded and less beveled around the outside edge. Also the bolt to adjust the cable is a pointed one compared to the old style you have of the screw with bolt round it.
The campagnolo script in the ones Gaston posted as just been enameled blue by someone.
But I believe that the Colbolto versions are basically the same as the second super record brake callipers (version 2) with the additional blue cap added, no??
