that was repainted? (a retorical question the painter actually applied a Columbus "repaint" decal) it is in rough shape looks like it was used either for cross or a trianer. the decals look like they are from the early '90s. if it is a '85 Campione it is not SL. all the 85 upper end bikes except the Centenario are Columbus Special, Tretubi, or Alle combinations.
for what it is worth the 85 Campione was specced with the afore mentioned Equipe brakes, TTT bar/stem, Super Record crank with N.R. rings and G.S. BB, Victory- pedals, seatpost, and hubs, N.R. derailleurs. the orginal rims were Mavic GP4
