folks. I just recieved an old Brwnng. 12 ga., semi automatic, from a deceased relative. It's pretty old and has some very curious markings on it. One on the other side of the bolt says : "Fabrique Nationale D'Armes De Guerre Herstal Belgique" What the hell does that mean? It seems like every part has a little stamping on it too. Is this thing worth anything?
