This is a Singer 201-2, one of the best machines that Singer every made. I have one that had an external European motor to it. I removed the motor and now the machine is in a treadle. It is the smoothest and quietest machine that I have ever used, and it produces the prettiest straight stitch I have ever seen (top and bottom thread). Looks like you are missing the spool pin that sits on top or do you still have that? Go to the Vintage Machine shop on this site and look for Billy's tutorial on cleaning this machine. He may have instructions on how to clean the motor pots which will need to be done(easy to do). If not he can instruct you on how to do it.
