Hi. My first post. I just bought a really cool little clock/radio gun safe today at a yard sale. The little old lady I bought it from didn't know anything about it (it was her late husbands). After some internet research, I think it is a Gamma III Safe and Sound. The radio works, and it looks like new, but I cannot get it open. It has two locks and I have the keys, but it also has a combination keypad. The locks turn, the keypad is lit, but it obviously has a combination which I do not have. Any help ??
