Nice box! I'm a big Proto fan myself. Finding a good, vintage heavy gauge steel toolbox these days is tough. Everyone uses plastic, which unless you've got just a handful of stuff, does not stand up. After scouring locally for one for years, I finally found a 1970s Craftsman one my Granddad had, just holding hardware. It took a lot of asking, but he finally gave it to me. I cleaned it up (I probably got a gallon of gunk out of there) and put my tools in it.
