Wait... wait... wait... I think you are confusing the back of the Sandy helmet with the back of the RotJ stunt helmets, which do have the keyslot area painted on.
Unless I am getting confused too, I believe this is the back of the Sandy helmet.
I was going by how the helmets looked arranged on the table. Since there were three helmets on the table with the Sandy in the middle, the shots from the back only show the two rightmost ones. That made it look like the Sandy was on the left. But now I see the photo named. Doh!
I guess it's this type of poor detective work on my part that's the reason why the Scooby-Doo bunch didn't want me in the gang. LOL!
Heres the two pics you referenced bud...looking at the one you thought was the back of the Sandy was in fact a ROTJ stunt
its in the second pic on the far right
no this is definently a silver left gaunt i remember thinking that could be jangos then i noticed jango didnt have the key pad(this was some years ago) So that fact alone made it stick in my head ,
i know i must have the pic some were but it will take agess to go through all my mags and books but i dont think its in a book maby an old sw mag one b4 insider started
