Unable to comment on whether your revolver is a fake or not. The Taurus revolvers from Brazil were very similar to S&Ws, but did not copy markings. The "Marcas Registrada" marking on an true S&W was placed there due to widespread counterfeiting in Spain in the 1920s.
I do not know about Jordan, but a counterfeit marked firearm is illegal in the US- Federal law requires guns to be marked with name and country of the maker or importer.
What we have here is... failure- to communicate.
