In that case, CFO's ROTJ is the one with the least amount of alterations. I believe that it has everything original except for minor detail parts. Kind of like RS, but without the sculpted forearm. It's from the Cameron Oakley moulds taken from an LFL made ROTJ suit. It was missing the right arm, so that should be doubled up. But CFO may have sourced another ROTJ arm to replace the missing arm with. I don't recall. Either way it's the same origin as TE and all it's derivatives except that TE only borrowed the moulds, and CFO managed to buy them. TE later on managed to source an arm from the special edition suits to use as the otherwise missing right arm, which is one of the differences between TE2 and AP because TE2 has the SE arm and AP does not (which uses two left arms).
