I would steal $40 from a Salvation Army donation jar a la the "Sticky Bandits" in Home alone 2 if I was flat broke, to be able to purchase that box at that price...
(before the morality police arrive, I am kidding!!!)
Serious time...I'd ****** that in a heartbeat. I don't see many Proto toolboxes of any style or condition for sale with any sort of frequency, and like stated previously, I love the classic look with the riveted on Flying Lady tags.
That box looks clean enough to eat off of, it was either someone's pride and joy or was in storage/sitting unused most of its life.
I would have no space for it either, but being that nice I'd have no qualms to use it as inside the house tool storage, displayed somewhere with pride. Take this with a grain of salt though, no fancy Gerstners used as jewelry boxes in my home...but my Kennedy roller is my nightstand, lol.
