Need help identifying safe!

[fireguy5oh]

Hello AL community.
Recently, a higher up in management had an old safe moved down into the main entrance of the admin building at my work, she said if we could open it, we could have whatever was inside. We tried movie tricks like using a stethoscope and listening for "clicks", but its such an old lock, its hard to differentiate clicks from rubbing, and resistance from friction of the dial. I tried lock manipulation, but had no such luck, as i dont even know the combination sequence. Like, left, right, left, or how many wheels are in the system. So i figured id start with the obvious, the safe manufacturer; only problem is, it doesnt say anywhere on the safe, just a serial number on the dial.

So, heres my question to the antique lock community, who made this safe, what kind of lock does it have, and what sequence do i input the numbers? Thank you all so much for any help!
