I have no knowledge of your machine, but the local fruit stand/antique store has a machine with your Art Deco decals. (Only yours are in MUCH better shape!) I don't know what it is-the name is worn/faded off the arm. The one I know is a 3/4 head, and I'm guessing it used to be a treadle-the motor looks added on. It also has a faded, brille piece of plastic in place of the front slide plate; apparently that went walkabout years ago. I go pet it once in awhile, but they want $300 for it, so it's still there.
