Complete Simplicity Antique Needle Case Store Display

An estate find in rural nebraska. I have minimal antique / vintage sewing items expertise, but want to share.

Simplicty Needle Case (Tin) in Very nice shape. Containing 128 wood cases each containing 2-4 needles. Estimate over 300 needles. On the inside lid is the interchangeable needle list, and a paper interchangeable list as well.

I have looked up similar needle case items and had not seem this item, Age of this item is unknown, estimate 1920's 1930's.

I think this is a rare (complete) to the best of my knowledge) sewing item find.
