ABC obviously doesn't know enough about firearms nor the legalities of such to address stuff, but I wonder if it was a registered machinegun or any bring-back paperwork. It's inoperable, but ATF might still want it cut up.
Please avoid the gun ban arguments, but what a fun little piece of history to find in a closet. I wonder how many are still in hands of Germans.
