I have looked at many pictures trying to find this particular "safe ? lock box ?" and not finding it any where. Back to the basic questions of, Age? Weight? How to figure out the combos (or changing thereof) of the 2 open doors?
Is there a way to count the holes on the dials to accomplish this? Last resort is to drill a 1/2 in hole in the back plate to line up the detentes. If I could just change the combos would be best. The nearest locksmith that would have knowledge of these locks is about 3 hours away from my location , not a very good return for the money to have him come in.

Was there a manual that came with these locks so the owners could change them or was that a locksmith only function?
