LAURONA SHOT GUN

I'm looking for information on a Laurona O/U 12 gauge. It is a 3 1/2 mag., and says Luger in gold on the bottom. The importer stamped on the side says Stoeger. When I contacted them they insisted they did not import this gun and refused any further information. I could find sites in Spain and Australia with guns having the same ingraving and apearance but not in the 3 1/2 inch chamber or 30 inch bbl. This gun is unfired, excelent condition and quaility. Any website or information would be great.
