It looks a bit like the 800 numers Berninas from the 1970s too, which where made and sold a bit into the 80s. The push button revese and stitch dials are a bit like the 1970s Husqvarnas. Some makers kept their models much the same for well over a decade, with minor changes. If the gears are all metal, or even mostly metal you have a nice machine worth sorting out.
