There is a vintage sewing machine group for Vikings, I think, on Yahoo groups. Some of those old machines are real gems.
However, if you don't really need the machine it won't necessarily languish without you; lots of people like to fix up vintage machines. I did it off and on for about 20 years, donating the machines to a non-profit that offers quilting classes. Getting a little old for that now, though. It's harder to get out regularly to shop, harder to lift the machines onto the table, harder to see to thread the needle, etc. So I'm retiring...
