What other period makers had models with the handle below the dial?
The only thing that comes to mind is the original Protectall, Mosler Protectall’s, and HHM/York/Diebold record safes.
I know this is no help to you.
Now that I’m thinking, off the top of my head, I don’t know any other US mfg. of cast iron safes that have.
