Helmet: Custom cast part
The Rest: Marauders Task Force parts

I wanted this V1 Astro-Viper to reflect the vintage card art, so I painted the helmet red instead of the retail black. Of course the backpack is not quite the same as it is only an exo-suit backpack, but it suffices.
Marauders Task Force doesn't have gold pieces, so I spray painted the small armor panels gold. You can't really see it, but I also painted the knee pegs silver to emulate the leg brace joints on the original figure.
