There was never a NR brake lever or brake set. Below Record/Super Record was Gran Sport. I can't remember if those levers were different than record or not, but they came with black hoods.
Just in case the OP gets the mistaken impression that all Campagnolo drilled levers are Super Record. it should be noted that Campagnolo also offered drilled levers on their Victory groupset. However, these are readily distinguishable from Super Record by their use of the Campagnolo shield logo with the winged wheel. Then of course, there all the aftermarket drillium variants.
Gran Sport brake levers looked similar to Record but didn't have the box outline around the brand name.
