These are the three different shoulder armor insignias used on the Boba Fett costume. The prototype pre-production costume was used in many of the first series of promo pictures for the Empire Strikes Back and use for the template of the first Boba Fett action figure by Kenner. All three costumes can be easily and quickly identified by the color of their wrist gaunlets. The prototype has rust red and yellow gauntlets, the ESB version has green gauntlets, and the ROTJ version has two red gauntlets. The "skull" insignia on the left shoulder bell of the costume was also different on each version of the costume and is shown and labeled on this picture.

Scan of Boba Fett costume shoulder bell decals. The decals were made using detailed reference pictures taken by Lucasfilm of the Boba Fett Prototype pre-production costume , Empire Strikes Back costume, and Return of the Jedi versions of the costume. Currently in use with the 501st, Mandalorian Mercs and Dented Helmet costume clubs.
