Looking further at this it gets more intriguing as theres actually some pretty unusual differences compared with the most commonly seen American designs:
1- instead of the doors central area being proud covering the front bearing and rotating gear as most American designs, it is actually the opposite with the centre area recessed utilising an outer ‘ring’ bearing and an unusual split 2 part crane hinge which is visible at the bolted joint in the centre of the picture.
2- the gear and pinion to rotate the door which would normally be concealed under the proud central plate are thus exposed and mounted externally on the front.
3- unlike most American designs it has an additional central ‘T’ handle (like their cylinder ‘bomb’ safe) to operate the locking bolt(s) which secure the door against rotation. Unlike most American safes which didn’t have separate handle operation and utilised a round bolt released off the timelocks or combo locks, this has the huge rectangular bolt visible at the ‘10 past’ position. What an oddball !!
Also, weren’t prints with a bit of ‘artistic licence’ pretty common back then? I recall one that you posted safeman, I think it was Hobbs, diamond or anti-violence safe where it also showed perspective/clearances that weren’t quite technically right.
