OP's levers have inked Campagnolo shields, as opposed to the engraved ones on that Chorus lever. Likewise, the black section of the lever body is aluminum with a gloss black finish on the OP's, as opposed to satin black plastic on yours.

This said - if the catalog photos are reliable, the '93s are shown to have inked/laser (how did they do them, anyway?) shield logos, and the '94s are engraved. That pegs SteveJ's set as '94 Chorus, but it backdates the OP's set to '93 Record/Chorus/Athena, as paulkal indicated.

If the side-script "Campagnolo" hoods shown in the catalog made it to production, the hoods on the OP's set have possibly been replaced, or Campagnolo changed them to the shield logo sometime during the year.
