Doppelganger Skin-- Leader of Men

Hello. I’m not sure where else to paste this down at the moment, but I’m looking for the Leader of Men skin for the Doppelganger-- brown and green in color. Reading from charts and different sources pointed me to Badass Torks, but none of them have dropped it. The closest I’ve gotten are two Bonus Packages and some vehicle skins. I’m starting to think my game may be glitched or bugged, as the same skin for Wilhelm, Athena, etc. seems to be just as impossible to find. If anyone can advise or trade with me for the skin, it’d be greatly appreciated. Thanks in advance for any help.
