Kinda fell behind on this thread.
Here's a few I've picked up recently-ish.
Old craftsman (late 30s), I have the larger version of this as well that has side handles instead of a top handle.
1956 snap on KR-25A, heavy box, needs some love, might repaint, but hate to lose the decal. At least the tray was there. Wish it had side handles like the modern KRA25s.
Interesting one, a Bell Systems small box, actually a snap on produced KR-259, 1962
Small 1/4" SK socket box
Finally a VERY old and in need of some help, Mac tools box. No drawer slides, I'd put it in the 1930's. Interesting tray design.

My 2 year grandson loves my tools!

Are they empty or full? Nesting boxes perhaps?
