The only thing I could gripe about, is the casting itself. It looks to be at least a second generation, from a silicone mold. Notice the soft distortions in the piece. These are usually caused by the silicone mold not staying securely in place during casting. If a better mold could be pulled from this one's predicessor, or a properly restored copy, this could indeed be the Jango equivilant to the mystery helmet. Seriously good find.
