Found a 1992 Autocar article with some photos as Peter Robinson took Nino Vaccarella back to the Piccolo Madonie circuit.

Makes me want to disappear into the Sicilian wilderness and spend several, well, years learning the circuit and its legends.

The circuit is number one on my all time 'Must drive' list.  Going over some books last night, it was fascinating to read over how successful the original Giulietta SVZ and SZ's were in events such as this.
