Nouvo Record was a standard longer- and more of an advancement when it was first introduced in the mid 60's I think. It was the Campagnolo standard among racers and tourists through most of the '70's until Super Record was introduced- Super Record is mostly the same basic designs taken to newer sleeker levels-

I left the sport for awhile when Super Record was still the pinnacle- in my opinion it will always be, and it gets the highest price on ebay-

but the Campy started changing it's lines more in the mid-80's or so, and under much more mass marketing competition from Asian manufacturers.

There has never after been a standard so universally widely used as was Campagnolo Nuovo Record gruppo and components through the 60's and '70's.

I bought my first "full Campy" bike- with Nuovo Record components in 1971 for $400. a decade later a similar bike equipped with all Super Record stuff would have been selling for about $1200- Mostly a demand kind of phenomena
