As I know so far, VashDStampede is working on these ear decals (the inverted "U"'s for both sides), but that's a matter of time, cause probably he's working on the Jet Pack decals first, to then to work on the helmet ones afterwards.
We have no updates as of now about these from him, cause I was helping him out a while ago, and that's the last he said about it. Let's see in the near future what happens, or you could PM him for details.
Would these help anyone? They will print out actual size. I tried them on my Deluxe helmet and they fit great. I just need to find some gloss, adhesive paper to print them on. The shape on the white curve is to compensate for the ridge of the ear piece. When you stick it on, it lines up straight.
Let me know if this doesn't work and I can fix it.
That's the ESB helmet , but it was used for a few shots in ROTJ SE when they added new footage. believe that there was an ESB helmet in ROTJ in a shot o two, but may have been an ESB stunt helmet. there's a thread on the topic.
