In most cases, the catalogs continued to call the group "Record," with the group containing several "Nuovo record" parts. The first part to be called "Nuovo" was the bottom bracket, which got grooves to shed dirt. Then the change was made to the rear derailleur, as noted. The crank changed bcd, but never changed its name: it remained "Record" throughout. Campagnolo never introduced a "Nuovo Record" group, rather, they upgraded several of the individual items in the "Record" group. Keep in mind that the concept of the "groupset" we have now was really developed in the 70's into the 80's and didn't really exist in the 60's.
Incidentally, the 144bcd cranks were in existence in the early 1960's, at least in the pro ranks.
