here's some more Follis stuff from Wooljersey, a reprint of a review of the 1973 model 672 that came Campy-equipt (and got very high marks from the writer. Thanks to Robert Broderick for the scanning and posting)

This model/year may be a bit newer/higher than yours (assuming yours is an early '70s 472) but shows what the top-end Follis from '73 looked like and how it was outfitted..check out the "drillium" rear dropouts, looks sort of like the Italvega/Torpedo treatment.
