I allready know the vault is empty(darn it), It was the weapons vault for the marine Reserve. It is built as an integrated part of the building, the walls are steal reinforced concreat filled cinderblock and solid concrete cieling best I can tell, the room is about 15' x 30' and there is a vent hole in the wall next to the floor that I was just able to put a telescoptng mirror in and look around.
There is a cage door on the inside of the vault door that will not let me see the inside of the vault door to see if there is a safty latch inside to open the door with. I have tried the standered shipping combnation of 25-50-25 and it did not work for me (the reserve told me they always reset the combination back to the standered combo when they leave a place), but no luck here.
Someone asked - I am in the Texas panhandle
