A 72 Paramount would have been all Nuovo Record - the very top components of the day.

Super Record was introduced in Campagnolo Catalogue #17, dated 1974. The earliest version of the Super Record designated cranksets were specified with Titanium axles. That turned out to be a disaster (the axles broke), and soon they were again fitted with the simple Nuovo Record steel axles. As Cudak888 mentioned, apart from this (now highly collectible) fluke, the only difference in the complete crankset assemblies were the chainrings.

The early Super Record group as a whole was a bit lighter because of the general use of titanium parts... pedal axles, rear derailleur pivot bolts, hub axles...
