So I know somebody that does estate sales and he basically has an old ammo box full of what he thinks is WW2 era stuff. He is clueless so I have no idea what it is either. Is it legal for him to sell it? What are the risks? should I offer $5? I see old stuff for sale all the time at gun shows. He is basically worried about liability. Or should I just keep my trap shut and never bring this up again? Wanna kill these ads? We can help!
