But I believe the tapers are the same on the old and new Campy stuff. Not sure about bottoming out on the spindle shoulders though.

I have a set of modern ('08) Record Pista cranks that I run on a modern Centaur triple cartridge BB (111mm symetrical). However, my old Campy N/SR (1981) double cranks will fit just fine on Centaur's BB taper. Likewise the Pista cranks fit just fine on the old "68-SS" NR spindle. Of course the chainlines are screwy, but the taper is the same. IIRC, the Pista cranks give a chainline at about -47mm on the old spindle, (and it is probably 1-2mm less, as I have never torqued it down). Whereas with the Pista/Centaur setup I get a nice 43mm chainline which matches exactly (delta is less than 0.3mm) my Formula hub and EA steel cog.
