Ardessa became Traditions and Jukar became CVA. Would seem those are brand names to better fit the US market. Probably the case that each company exists as a north America division that functions as the importer from Spain. Parts interchangeability between the manufacturers may be unintentional, but it does seem most older stuff looks like current. Could be some changes though...
Bergara barrels are in the component mix for one or both, but maybe only for their inlines.
