Checkout Nova Montgomery’s website. Many repairs and maintenance items can be done yourself. I have two featherweights. They do require frequent oiling and occasional lubing. They have a beautiful straight stitch, but no other stitches. Featherweight machines are not light compared to today’s machines. Although mine have original cases, I choose to use a rolling suitcase when I take them to classes. When they were manufactured, they were created with two different electrical types. One for the USA and one for England. Make sure that yours will be appropriate for you. I love my machines.
