Please help Identify Campy Bottom Bracket

Hi all,

This is out of my (small) areas of expertise, and I'm not sure it matters too much, but for curiosity sake I'm wondering what this BB is? And how you can really tell these apart. I've done some searching and read a bunch of threads but haven't found a definitive answer.

The BB comes out of an 1989 Italian Bianchi but it did not come stock with a Campy BB.

Alloy (silver) spindle measures 115.5 (best I can measure it, could be 155 or 116) and is marked 70-ss.

Bearings measure 3/16, and cups say Campagnolo, BREV INTER 36 X 24F on both.

Late-80s mid level BB? Whatever it is, it's a nice BB.
