Super Record trumped Nuovo Record (SR - NR), though SR wasn't available as an option for some components. So there would be SR cranksets and NR cranksets, but where there was no SR - NP options, the component in question would be called, simply, 'Record.'
The SR components usually were lighter than the NR components for the same task. For instance my SR crankset has more area cut out of it than does the NR equivalent. So most racers would want SR where it could be an option. This continued into the early 1980's as I recall, then I stopped paying attention when all hell broke loose and new gruppo names were launched faster than cockroaches could invade an apartment building.
