What year was the Husqvarna Viking 4700 Sewing Machine Manufactured?

" Year of Manufacture for a 4700 Husqvarna Viking Sewing Machine: Their answer: "year of manufacturing is 1990"

...WRONG! I just purchased a Husqvarna Viking 4700 Series, has an inscription stating made in "West Germany"...made in the 1990's? I don't think so!
