Morning (afternoon? night shift thing)
Man, jump off for a few hrs. and we go from a free WDW trip for a few of us to Walt's suite- & now, a Land/Sea pkg. for everyone

You're a hoot!!!
Update-called in some cavalry. Right now, there are 7 of us "safe geeks" looking into this. Will keep you informed on finds.
Someone asked about the patent info (sorry forget who) dates listed on lock. The first date of Sept. 18, 1860 is when the patent for that combination lock was filed. The 1866 dates are when improvements to the original patent were filed. Exp. 7yrs-the patent was set to expire 7 years from July 14, 1871 (so 1878). An expired patent means no royalties to the inventor, and the item may be copied and sold at will by anyone. Those dates unfortuntly can not date the safe (other than it was later than 1878)-they date the combo lock.
Am still looking.
As for moving it-buddy suggests duct tape on floor with a spray of wd40 on tape and wheels (if on it).
What is taking so long on the info: Baum filed a bunch of patents, most of his safes were smaller (about the size of a bed side table), the majority of the larger ones were double door safes used in post offices and banks.
This one is HUGE and is a SINGLE door. It doesn't mean anything value wise-but to us "safe geeks" this is...drool time.
And for those of you who are worried that the saga will end with the opening of the door....the top safety deposit drawer is usually either combo/key.
