When that arm shape arrived, conical nuts came with it. The Gold capped nuts of course were only for the 50th special set, I am leaving out other details like the stamped identification on the arms.
My Eddy Merckx that Eddy sent me as a complete bike from Belgium in 1983 had the Super Record brakes with the calipers with triangular cross section (as per Anniversary caliper), Campagnolo script logo, and conical-shaped nuts for center bolt lock nut and cam lock nut.
