I found another current maker of round vault doors. While these are newly made, they are patterned after antique doors, so I think they might be of interest here. And a door of theirs seems to have fooled me.

The company is Industrial Evolution Furniture Company. While they do make round and rectangular vault doors, their web site warns "Our doors are very secure, but are not true bank vault doors." This is why I put Vault Doors in quotes in the thread title. Their web site shows samples including the Watermark Hotel in Baton Rouge, Louisiana, which I had earlier identified as a Mosler door but now I think it may be a counterfeit door.
