I am a Bernina fan and I just bought a Bernina 930 for $25. There was just one foot and no case, but the table part is there and I have taken it apart and cleaned it which by the way it was hardly a speck of dust or lint in it.
It has a silver bar on the front and by the manual, it looks like the thread goes under the bar twice be for it goes to the take up lever. I cannot figure how you get the thread behind the bar. It sews wonderful with the way I have it threaded and I am thinking I just cannot see the thread in the picture and it is really not behind the bar. I will be searching for feet. It sure seems like I have stumbled across a real jewel. I walked away thinking "Whoopee".
