AIA #4 clone proofing

[Dimitri]

Perhaps the "Brisbane" refers to the location of the company.

I would agree but all 3 countries (Australia, Canada and the United States) require the country or place of manufacture to be marked on the firearm for many years, just as the majority of Europe also requires the same. Hence why I am going to say if AIA would claim what you are now, its just more misdirection and misleading the purchaser of where the rifle (and in specific the receiver) was made.
