Sewing Tools in Antique Box

This is a really neat box I found in an antique store years ago. The unusual ends caught my eye.

When I opened it up- wow! Sewing machine feet that actually fit my Singer! I think the whole thing cost $10.00. It is lined in plum velveteen.

I don't know if the contents are original because the clips have numbers on them and only some of the attachments match up.

This collection of rolled hemmers all have corresponding numbers. Also in the box are a ruffler, zipper foot, seam guide, and quilting guide.
On the top of the box it is marked "patented 1889 February 19". Pretty neat!
