do you mean the arrows? I think only the ROTJ helmet has painted arrows, but im not 100% sure on that. For the story behind that, it beats me. I think theres like one of those diagrams that point to every piece of fett's suit that says something about it, but I dont know about the arrows
There is the ears lid which i think you are talking about. Its the prepro 1 version if i,m not mistaken. I have also included the eyes version as well. I am never sure if both of these are classed as prepro 1 or not ????
