Full-Campy, Nuovo/Super Record, 531 racing bikes were typically around 21 lbs with tubulars. You could get the weight down to sub-20 lbs. without too much difficulty, especially in smaller frame sizes and using ass-hatchet saddles. One hopes that there won't be butchering and drilling of classic components for the sake of this little farce.
