Sorry, I'm not following you. What does "Fast Jack" mean? Is it Fast jacket??This one is the Fast Jack one. There's another IH colored one that came with the IH Juliet. It's exactly like the one that was sold at the vaults that isn't colored.
Is the other IH coloured one you're talking about different from the pictured one?
Also, thanks @Blockster, @Dallas O Hog, @dragonvoi and @supersharp for supplying pictures and information. I've updated it now.
