That is a Singer 114W3 and it does freeform embroidery. It lays down a chainstitch and you maneuver the work piece to draw/write, it's very cool and very old.
Last image from tonight (short film in the morning): this brother out here with his Singer sewing machine, gifting people a custom embroidery on their jerseys and hats with the name and the date, was more artistic than anything at Burning Man and ad gorgeous as a Caravaggio.
Magic!
Goodnight.
