[QUOTE=yoav;2926667]A BB from that time probably has loose ball bearings. Whilst state of the art for that time, a cheap modern sealed bearing square taper BB is probably better.

I disagree, a Campagnonlo [or any other quality] bottom bracket with loose balls properly fitted up and with no detremental wear will be 'better*' that a 'cheap' modern equivalent. However, the sealed BB has the advantage that it requires no skill to fit it. fit, forget and replace.
