That is a safe that Browing/Prosteel used to sell. It was not built as a gun safe, but is a retrofitted fire rated (document) safe. They did not sell them for very long. Probably made sometime in the 90's.
Can you or your friend look to see if there are any UL tags that mention a fire rating? There are currently no gun safes on the market with a real UL fire rating, but if there ever was one, this would be it.
