Nomad
The Nomad referred to went to a small Victorian country museum - Ballarat?, Bendigo?, Benalla? One of them has a small collection.
The Spitfire, I have been told, is a "Bitsa" - a collection of bits from various Marks assembled. It was on display in the RAAF Museum for some years.
Almost anything can be made airworthy these days ... if you have enough money, a makers plate and can buy the expertise. This Spit must be a better start than some have had. Take a look at some of the relics advertised and featured in Classic Wings Downunder or Aeroplane (Monthly) and wish really hard. If I were a rich man ... deedle deedle deedle deedle deedle deedle deedle dum.
