I assume you mean this. Well the story is al kind of bullshity, but here we go...
1991 - Ric Flair beats Sting to become the NWA Champion...also in that match Flair became the first WCW Champion (though WCW didn't have a title belt, they just continued to use the NWA Title, as he was also the NWA Champ at the time). The NWA belt at this time was "The Big Gold Belt" design currently used by WWE's "World" Title. Anyway,. July of '91 Flair goes to WWE, but Flair brings with him the NWA World Belt - which for all intents and purposes was acting as the physical symbol of both the NWA and WCW belts. SO, NWA after a year so decides to hold a WCW/NJPW tourny to crown their new NWA World Champion, using a new belt with the same "Big Gold Belt" design which was won by Masahiro Chono...WCW on the other hand had Dusty bring up some regional title belt which they put a plate over it to read "WCW" and that then became the official WCW World Title, the belt your refering to. (by the way, Lugar won it originaly)
As time went on the NWA World Title found it's way BACK to Flair after he had returned to WCW. However at this point WCW left the NWA, and as such they had floating around their WCW World Heavyweight title and Flair's NWA World Heavyweight Title. Somehow the taped segement of Rick Rude winning the NWA Belt got leaked and so the NWA no longer would honor the title change as legit. The NWA belt now completely seperated itself from WCW, they began refering to the NWA belt (now no longer honored by the NWA) as the "International" World Heavyweight Championship. This was all very confusing and everyone wondered why one promotion had two world Champs, so eventually Flair won the WCW belt, Sting was the International World Champ, and they wrestled to unify the belts into one...which Flair won.
From that point, they dropped the WCW belt, and continued on with the "Big Gold Belt" as the WCW Title.
Hope that made some level of sense. The short answer to your question is the belt your questioning is actually the "real" WCW Belt from 1991 to 1994.
