I don't see much rust. The needle plate could be removed and polished. The upper part before the tension could probably be removed, polished and replaced easily. The pictures are too small to see much more.
I would not recommend a quilt on it, unless maybe a doll sized quilt. Flannel can have its own set of difficulties, as it tends to ravel more than good quilting cotton.
We like pictures. In order to post pictures on Quilting Board, you will probably need to reduce or compress the picture to a
file size that is smaller than 2MB. How to post images can be found at

I have found that only the big red "
Reply" button works to give me the
paper clip icon to work for adding pictures.
