This is a loose TopToys figure produced in Brazil during ROTJ. These figures are very hard to find especially in decent condition. The figure has no pegholes and you can see two circles on the thighs from the mold – both key indicators of an authentic TopToys figure.
The cape is much darker than the Kenner cape and the neck is folded left over right, opposite of the Kenner sewn capes that are right over left.
This figure can be found with the brown palace blaster or the black stormtrooper gun. Both very different from the Kenner release.
The lightsaber has no bumps on the hilt as seen in the comparison photo below, the saber on the right is a Kenner release.
The last photo is of a well known TopToys experts collection which confirms the details of the accessories.
