Nice find. Based on the overall look and style, looks like it might date from ca. 1930s-40s, but hard to say for sure without a serial number (even then not an exact science with a Mosler). Is your primary goal to get it working again? If so, given that the door is open you could simply observe the wheels while dialing with the lock internals exposed and thereby figure out the current combination.
