The safe was made by R&D enterprises; they made several safes for the car and this wall safe. I think they have went out of business, but I also heard they were going to start up under a different name. Here is their last known info;

It's too bad their not in business any more, they had great USA made products and I wanted to buy another wall safe from them. I just called their 800# and got a recording about their " Cargo container lock box" and was told to leave a message. I'm going to call tomorrow and see whats up; they must have had legal problems with their old name, which was Handgun lock box.
Great products with simplex locks.
