Thanks for that site Mike!
I was in Darwin in July, and took a whole heap of pics of the Sabre they have there.
Some of these pics showed a hint of green, maybe chromate or interior, in the wheel bays, and it appeared it had been sprayed over with silver.
The pics on the web site proved to me I wasn't seeing things.
I also have a niggling feeling that the insides of the wheel bay doors would have been finished in the same greenish colour, but so far haven't been able to find any real proof of this............yet!
The search continues..................
