We have a lot of work to do on this machine. At the time of this writing, we have not been able to use the machine because it did not come with a foot controller and we have been unable to properly wire up a replacement. We managed to trip the house circuit breaker in the process. We were able to find a wiring diagram--thanks to the yahoo group VintageSingers.
This machine has a band around its arm where the paint has been picked away by its former owner using a wristband for pin storage. The S and I are nearly gone. We prefer to use magnetic pad for pin storage.
A tension issue on the 201 is the bobbin. It HAS to be threaded exactly right! The thread should be coming off the bobbin so that it unwinds CLOCKWISE. This is a must for the 201, other machines are not quit as fussy about this.
