I’ve mentioned it, Nekoman’s mentioned it, there’s two different COBRA Trooper molds used by The Black Major. One from the early days, 2009-2011ish, and one from 2014 to the present.
First Mold: Foot and backpack holes that don’t fit normal foot stands or backpacks. There’s less of a “club foot” appearance. 82-83 markings
Based on legs, mold resembles 2000s era Night Watch figure
Available in: Blue (Red or Silver logo), Crimson (Cobra or Red Shadow), Arctic, Black (Light Grey Webgear or Dark Grey Webgear/Face Mask), Jungle Camo, Urban Camo, Desert Camo (Red or Black logo), Tan (Desert Scorpion or Red Logo), Blue (Red Mask and web gear. Different shade of blue), Stinger Grey, Night Viper Green (Outrider Memorial Figure)
Second Mold: Club foot, backpacks and battle stands fit the figure. Generally have inverted rivets, and tell-tale paint app in the centre of the garrotte on right arm. Arms don’t always sit flush with the torso (Think 1984 Recondo or 1989 Night Viper). 2016+ markings
Feet are more reminiscent of the 1982 COBRA Trooper
The second mold appears to be the same or based off of the first Mold used for factory custom Troopers
Available in: Blue, Python, Orange, Olive Drab, Grey, Neon Green, Pink & Purple, Action Force Hunter homage, Black with Red web gear, Tiger, Firefly, Soldado, possibly others, with various variations of logos and highlights.
Second Mold is on the left hand side in the images.
