This Gold Tiger was painted by Alex (alexdakar) on the Treefrog Forum for Nasir. Julie has posted the comment below for informational purposes.

We recently were able to aquire a GoldEdition Tiger that had never been out of the workshop in Buenos Aires. It was made by the sculptor to promote the new Gold series.

There weren't that many Gold Tigers produced...making this a very special item. 

Actually, this is a sample tank that was painted in desert camo. It was made prior to the other Gold ones (to show what they could look like).
