Hi Dr. Saul,
Brinks safes were purchased by Honeywell and your safe's combination will be in the owner's manual that came with your safe. If you are unable to locate the manual you can contact the company at 1-***-***-**** and request they send you the combination.
Also their website can be of great assistance:
Because of safety concerns, only the safe company will have your unique combination for the model that you own.
