My daughter works for a company that goes in and cleans out repossesed houses, etc. Today she called me with the news that she had acquired an antique sewing machine. It is black withgold inlay with the model #D40604 on a little brass (?) oval plate on the front and the name Universal all over it & the patent number says Universal-Japan. Can anyone tell me anything about this machine like age, where it comes from, etc?
