Many years ago, my mother's neighbor said that she absolutely had to go to a certain store, like Sears, Montgomery Ward, etc., for different appliances. She told me that the store brand appliances and electronics were actually made by brand name companies, who put the store brand logo on the machines. The point being, store brand appliances were exactly the same as the brand names but in most cases, were a lot less expensive. I, for instance, have a Daewoo Television set, which was really made by Sony. My son has the same exact tv, but it cost him considerably more than mine, just for the privilege of having the Sony logo on it.
Sooo, I wonder who actually made the Kenmore and/or other store brands of sewing machines. It might be useful information because if you can't find parts for your machine, the original manufacturer may still carry them. If anyone has any knowledge of these companies, I sure would love to know.
