It might be a snap on box. The pics aren't that great, and it looks pretty rough. If it is a snap on box it would be a KRA-53, which is a pretty small box in the first place. ~20"x10"x10". I'd have to see what it looks like in person to make a decision on purchase.
It's missing the badge, lock, lock bars, looks like damaged to the lid corner. Front possibly doesn't fit right. If the drawers work perfect, maybe. But there are alot of negatives that will be time and $ to fix.
