Putting a makers name on a new non original set of barrel is not fraud unless it claims they have been made by the maker . If that maker has been out of business for 50 years then there is no way that they could be original .In the case of a company still in operation it is only fraud if the claim is that the barrels were made by the maker.I have seen many classic and vintage cars that have been totally rebuilt with non original or patten parts or that have new parts made . But it is still shown as a Bentley ,Morris or Ford .
