Such wonderful memories Brandee's mom! Very nice machine and cabinet. And....someone in your grandmas life had a bit of flare! Replacing the original knobs with the red handles. Maybe grandpa did that as grandma got older and her arthritis made it hard to grasp those little knobs.
I can can tell you....yeah! You still have the front slide plate!
They are so often missing. Of course others on this list can tell you volumes more than I can, but it is a full size Singer with the Vibrating Shuttle (VS). The bobbin looks like a bullet....do you still have it? Do you oil your machine and treadle it occasionally to keep her limber?
