This ones a beauty, seriously had to look twice at this to check i wasn't seeing things!
Initially it was simply the Safe Co name that got my interest, then, seeing it was only a HHM safe it almost got deleted to move onto the next...

Knowing of the early Hibbard Rodman Ely bank safes with (rectangular) boltwork I was under the impression that they were alone in this respect, believing the others all used either screw action threaded doors or breech-lock lug doors, which then secured against rotation.

This ones a beauty- round bolts, horizontal pressure bars, hexagon bolts around the inside of the boltcase -it's like a miniature HHM vault door in a freestanding square body.
