It's been restored over a long period of time in Australia, but is more or less complete now. There have been rumours for ages that it would stop off in the UK en-route to the US, although this seems to be a very long way round. If it is at Duxford, I'll be a very happy camper. There aren't many twins on the UK airshow circuit, so the possibility of seeing two never-before seen aircraft at Duxford is indeed mouth-watering.
