I love the Iron Curtain reskinned stock minigun (awarded via "Poker Night at the Inventory"), and have put a Professional Killstreak kit on it. I'd really like to strangify it too, though, and there don't seem to be any Iron Curtain Strangifiers on the community market. None of my research has shown up any such thing... but nothing has proven it impossible either.
Do strangifiers exist for all weapons? Or alternatively, is there such a thing as a "generic strangifier", able to be applied to any weapon?
