I’d say the ATF. What resources can they bring to bear to help? I don’t know, but I’d sure find out. I might get a guy that wants to make this issue a project. It’s not cooperating with the enemy. Were I in Glen’s shoes (God forbid), I’d want to shout from the rooftops that my stuff was ripped off. Every interested eye is better.
And, as I've already show, the ATF doesn't get involved in such matters...
