The other night I began questioning Steven about this box. Where did it come from? What was it used for? Why is it SO heavy?
My husband doesn't know who it belonged to or exactly how old it is, but thinks it is possibly around 30-40 years old. (He rescued it from the trash pile!) He told me that years ago, before there were portable plastic toolboxes, wooden boxes like these were a carpenters "portable toolbox." They kept all their nails, screws, drill bits, small tools, etc. in the little compartments. See the holes in the top on the picture below? That would have held different bits for screw drivers or a drill.
