Sewing machines seem to have ( longer lives) than many items, I've heard 100 years or less is vintage. Over 100 ( might) be antique depending on the machine & who is appraising it. I have a machine that is 102 years old, in good condition, still sews beautifully, and was told when it was appraised for insurance that it's a very nice Vintage machine. When I asked about it being an antique the response I received was -- "just because something is old doesn't mean it's an antique ".
