I'm not sure which is metal, but the Australia is the same ship that appeared in the BCH listing in the rulebook - the decals give her away.
Firstly, she's mis-spelt - 'Austrailia' rather than 'Australia'.
(Trust me, I know about these things... :lol: )
Secondly, there's a small 'chip' out of the top of one of the 'C's in 'NCC'.
I'd be more than a little startled to see both these errors perfectly repeated on two different miniatures.
