Judging by the surface finishing coat, I'd guess that it is Athena which, in this version, was made from around '88 until '92 or '93. Athena was ranked third in the Campag hierarchy at the time - below Record and Chorus. Still not one of Shaun's real experts but I have a complete '88 Chorus group and the finish is distinctly different.
That looks like a painted (rather than polished) finish - that makes it Veloce I think. certainly looks very similar to the 94 veloce group (going by the catalogue pics). Athena and everything above it (CdA, chorus and record) always had a polished finished as far as I know
