It’s really hard to say from these pictures. They’re not in focus and it’s hard to tell what colour this is - metallic green, like a Mercury Cougar? But as far as I can see, it’s the later version of the Corsair with the unpainted base, so it’s probably not a prepro. The rivets look good but it could easily be a repaint - better pictures needed, preferably on a white background.
Please use a web hosting site (like photobucket) to store pictures so you can post them here, using attachments makes it hard to view the pictures when you have to scroll to see them. Seeing comparisons of models is hard to see with attachments too.
