The Safe Cabinet Company of Marietta, Ohio appears to have opened around the time of the First World War, and does not appear to have made it to the 21st Century.
The doors appear to have individual latches/bolts. Which are likely vertical in nature, as nothing is revealed in the astragal (the fancy term for the overlap on the RH door).
From the few catalogs from SCC, the "A" and "B" models had UL Fire ratings. Also, the stock colors were either black or olive drab with gold pinstriping. And, that's a Yale combination lock, so this beast had been restored at least once. Whether that makes it worth it the effort and expense of moving it, I can't tell you.
