Cool, never seen that before.
I still haven't had much luck finding similar boxes in my searches.
The thing's a tank. It weighs a ton. I had to unload it from my truck bed using the tractor.
Most of the drawers have a single built in divider, either back-to-front, or side-to-side.
Each of the drawers has a tab lock in the center of the handle (you can kind of see the in the picture of the full box). Slide the spring loaded tab to the left to open the drawers.
No keys (the one pictured fits, but doesn't turn). I think I'll take the locks down to a locksmith if I can find one that can make keys.
