Help to identify an Antique Wooden Chest with assorted compartments, heavy, 32"/16"/7.5", if it's a toolbox, what kind?

Hello everyone, I got this toolbox about 20 years ago from a yard sale, but I can't tell what kind of tools it was designed for. It is big and heavy as it is, without the tools, but it has a leather-made handle that suggests mobility. Three locks and copper/brass looking corners, chain to hold the lid up... It is too narrow and wide, in my opinion, to hold conventional tools, but I don't know much about the toolboxes.
