I bought mine, fixed it up and it is ready to go when I want to play. It doesn't get much thread though. I am always after a broken one.

Vigorelli Fix up Question
 

I know that it has been a long time since you first posted, but I am curious about if you got your machine unstuck? I have recently purchased the same machine for $20 and would love to see it working. The needle bar will not go up and down. It now moves from side to side and the front knobs work too. Any suggestions?

There are a lot of close tolerances in this machine. Have you opened the lid off the top? spend ten minutes on it with a hair dryer on hot and it may melt old oil. then see if it will move. it may take a fw tries. then add oil to everything that moves or should move. The top screws are kind of neat with oil holes and holding down the lid.
