I would think that is a mislabeled Rodeo, mislabeled by the factory. Just like if you ordered a Single Action Army .45 from Colt and they sent you a Single Action Army .45 Colt but the box said Frontier Six Shooter. I could be wrong though, maybe USFA called convertible Rodeo's Cowboy Convertibles and the Cowboy in Cowboy Convertible has nothing to do with the regular Cowboy model.
