I clean up machines like that to donate to a local non-profit that offers quilting classes for the disabled. Many of the people cannot afford to buy a machine.
Can't tell you much about this particular machine except that most of the old machines are real workhorses and will last almost forever given a little oil. This one was taken out of a cabinet. If you decide to keep it, you will probably want to measure the base and check at thrift shops periodically to find a cabinet to go with it. The electrical cord looks in decent shape.
Edit: Actually, maybe not originally in a cabinet but rather in a "portable" carrying case.
