Cleaning out the garage and getting rid of some stuff and came across this old box. Was informed by my boyfriend that it was a machinist box that had been his fathers. I never heard of one, but thought it was very interesting/unique. I've been trying to search and get a little info on it, but can't seem to find anything like this. The inside lining is burgundy in color, I see no markings anywhere on the box except for the main lock on the top of the box that is stamped Corbin. There is an additional lock on one of the small drawers and I actually found the key for it in the box (looks like an small old skeleton key. I've included some pictures hopefully someone can help me identify the maker/age.
