This item is a posable action figure from the Revoltech series.  

Another great vehicle addition to Kaiyodo's ever-growing Sci-Fi Revoltech series! This time up it's the ever-popular Thunderbird 2 from the classic Gerry Anderson TV show Thunderbirds. No scale is given, but TB2 measures 21cm long. Includes a display stand, detachable cargo pod with Thunderbird 4, extension legs that can be posed extended, retracted, or folded, and a name plate. FAB! 

The metallic version can be found here
