There probably were some copper plated bikes in that lineup, but by the late 70's I'd bet they had moved to tinted clear coatings.
in italian there are three words for three process, similar but different: cromatura, cromovelatura, ramatura.
cromatura is obvious
cromovelatura is a process in two steps by bathing first in chrome, then another lightly coloured bath
ramatura is covering with copper
the wilier is worldwide known as the RAMATA, as much as many other bikes were CROMOVELATO.
then it is not a cromovelato copper coloured.
i don't know what chemically distinguish the two process, that's a fact. somebody in the business will make it clear one day....
