I have three Singer Featherweight machines, the oldest dating from 1934. They require regular lubrication. You can find a diagram on the internet as to where to oil your machine. It requires that the bottom be taken off to reach some of the spots. With regular maintenance all of mine run like a dream and I use them a lot to sew. The original owners of two of them were each of my husband's grandmothers and the third one I found at a resale shop buried under other stuff in a back corner. Was I ever excited over that and it is the 1934 one.
