I don't have much to add, but since it seems you were skiped over I thought I could at least give you a bump.
I found the ad, and personally think I would buy all of them if they were in good condition. Seem like good prices.
Top is a craftsman 4 drawer middle box
Second looks like a middle box, but I couldn't help you on the maker.
3rd looks POSSIBLY like a Beech top box. I forget who had those style of front covers, but they were specific. Great deal, best of the bunch.
4th Wards / Powr Kraft top box.
Sorry I can't be of any more help.
