Here are two different versions of Popy DX Yamato.  One's deck is painted silver-gray (both front and back), the other is copper-brass. (again, both front and back)   The color of the plastic bulb shaped elevation (in front of the ship where the front firing button is located) is also different, one is black and the other is blue.  (If anyone knows which is the first version, please drop me an email.)
