If you buy the airfix 1/144 scale Pan Am B727-200 kit you can then buy the decals from Hawkeye decals in Perth. They have TAA/AN decals dating right back to the 1940's for every airliner they operated
email

I remember when I was a kid you got Ansett and TAA 727 models from BP servo's when you filled up with fuel?
Hope this helps
