Maybe I should scratch around my work place ~ LOL
After all the Dairy processing works has been in situ for over 100 years AND the Australian Army DID set up camp in the building !! ~ processing butter for the troops ! LOL
BUT~ You just NEVER know !
( I was going to import a Bren Gun magazine for my WWII collection ~ from UK or even USA but I bet my bottom dollar that Customs would pick it up in the process and then I would be sure to get a visit from the Aust Federal Police under the latest Terrorism Act ~ especially as to what's going on in the World right NOW!! )
