I am interested to know also if George has initiated any correspondance with the Firearms and Weapons Section in Canberra (not just calling the generic 1300 number as they will have no clue at all) as it is almost certainly them that are presently in possession of the knife. Aus Customs are also known NOT to be the fastest moverers in the world. I have had a pair of boots held by them for over three months previously.
I think itd a good sign of goodwill for George to contact the PO or customs. Whos to say it wont work.
