I had a Kenmore for years that was from the mid 50's. It was my mother's. I used it for years until the belt which was a hard plastic became warped and it sounded so loud when I used it I let it go to Goodwill. Hopefully someone found a new belt for it and it is still running. It was just a straight stitch but had an optional buttonholer that attached. It sewed for a lot of hours and miles.
