Robert. I went to the TAA Museum last June (Photos posted elsewhere), and agree, there is quite a lot of Ansett exhibits there. Simple things like brochures and timetables I remember collecting when I was younger.
Also, any idea if you've seen that Ansett documentary DVD on sale anywhere else? I too have been after that, but haven't been overly successful.
Rest.... how did you folks get a hold of aircraft seats? Would love to get a set!
