I have my mom's green FW and my grandma's Centennial model. I went to the above website and bought David McCallum's dvd and book on how to maintain and repair them and did it myself! He sells parts as well. Easy, peasy little machines to work on and the instructions he gives are clear and simple to follow. There's not a better machine anywhere for straight stitch piecing, imho. Lucky you! Enjoy her.
