Campy Bottom Brackets - What do I have ?

I've accumulated a few used Bottom Brackets, and am trying to figure out how I can use them. They measure 102 mm, 111 mm and 114 mm

I ride double cranks w/ English BB. All Cannondales except my old steelie. They're all 68 mm BB shells. Looks like the distance between the cups on all 3 BB is also 68 mm. I measured actual spindle length with dial calipers, so ignore the camera angle distortion.

What cranks are these designed for ? Is that enough info ? TIA

Edit: They're all English thread.

102 mm:


111 mm:


114 mm:

Some good BB info on this page. http://www.sheldonbrown.com/bbsize.html
You need to know if the BBs are British 1.37"X24 (good) or Italian 36mmX24 (incompatible) to fit your frame.
You need to figure out if whether the spindles are ISO or Japanese standard, and which tapers are in your cranks.

I assume they're all ISO .. (?) (Everything is Campy)
The 3 BB spindles measure .495" or 12.5 mm at the narrow end of the taper. All the cranksets I have are about .480 at the narrow end, so they match in that respect. The spindle lengths have me a bit puzzled. Is the 114 mm for triples ? When would you choose a 102 mm over a 111 mm ?
