Get good detailed pics of the frame then we'll discuss it.
In the link provided BlueDevil is post a pic of the '83 catalog, the American market one I believe, and pictures of completely different bike. The catalog pic shows a Flat fork crown where as the actual bike pics show a semi sloping crown used on '85 bikes. Also the catalog shows Portcatenna holes on the right dropout and not are seen in the pics of the bike.
