It's hard to tell from the small picture, but it doesn't appear to be a "sewing machine".
The lack of a presser foot made me think it was a free motion embroidery machine, but its not.
The heavy chain presser foot lift made me look closer and see a sideways presser foot probably, which tells me it's a probably a button sewing machine or a possibly a bar tack machine.
So...as asked, what do you want to do with it? Find out a model number, but I don't think you want it.
