So I run a recycling center and a customer left this in my steel pile. I think it kind of cool and would like to restore it. Few concerns though. First, am I allowed to have it? If not, who do I call? Second, is it safe to handle? I'm also not really understanding what I have. The mk44 is a 30mm belt fed, the mk45 is a 5" projectile. Do I have a misprint?
