This is mainly about the 1967-1985 era, it seems to me that there are more than one way of naming any particular component.
First there is the part itself, Off the top of my head, I think it was only the the rear mechs that ever had "Nuovo Record" or "Super Record" on them. Most only had "Campagnolo", eg the seatpins and brakes (although the Gran Sport brakes had G.S. on them). And the hubs had "Record".
Right, a lot of the Gran Sport parts were marked G.S., presumably because they were superficially similar to Record in some cases, but generally of lesser finish.
Second; the name on the box. Eg, the Super Record front mech came in a blue box with "Super Record" on the box but not on the part itself.
Third, the groupsets as shown in the catalogues. Eg, the exact same Record hubs were included in both the Super Record and the Nuovo Record groupsets. So I suppose that's why people usually called them "Super Record" or "Nuovo Record" hubs.
I think that's where the argument comes a little unstuck. The catalogues never listed a Nuovo Record group - it was always just Record - and where the parts in a group were specified it was always made clear whether or not they were Record, Super, Nuovo, or even in some cases "Nuovo Super Record". The No.18 catalogue, for example, lists the Super Record group:
SUPER RECORD Road Group:
SUPER RECORD Road Campagnolo Group composed of
Super Record brakes
Super Record gear
Record hubs set
Super Record road chainset
Nuovo Record bottom bracket
Record road superlight pedals
Super Record headset
Nuovo Super Record seat-pin
Where there was a name on the part or on the box, it generally agreed with the description in the catalogue, hence the cranks are just described as road or track (STRADA or PISTA) but once the chainrings are attached they become Record or Super Record chainsets.
I agree that people make the association, which is why you get people selling "Super Record" hubs on eBay, and mistaking Superleggeri pedals (with steel axles) for Super Record (with titanium).
Calmes dans le demi-jour
Que les branches hautes font,
Pénétrons bien notre amour
De ce silence profond.
