Where would I find information on a Y and E Safe?

I have a two-door safe manufactured by Y and E. It has no model that I can find, but states "Y and E Dry Insulated Safe" on an oval tag riveted above the doors. I have the combination to it and it is open, but I am looking for more information on this company and safe. It is functional, but has a lot of dents in the outer skin which tells me that it is not heavily armored, at least on the outer surface. Specifically I would like to know what level of protection it might offer against a determined thief, and also (depending on that answer) whether it would be worth repainting/restoring it.
