Centaur crankset had a 111 bb designed for it, which was a cartridge BB. You can look on the website "www.bicycleclassics.com" to see if any of the spindles that are compatible with rifled cups are 111 mm. I suspect they are not that short. There's another site that has info on the full range of Campy spindles, but I don't recall what it is.

The Centaur BB and the very similar (dimensionallly identical) Veloce BB are (I think) still available, at least on Ebay, and they are a lot cheaper than hunting for used matched cups and spindles. Besides, the cartridges are the correct BB for that crank.

That crank is much less C&V than your Raleigh frame, if that matters to you.
