This is a replica of the lightsaber prop used by Luke Skywalker in Star Wars Episode V:The Empire Strikes Back. The prop was custom made by a fan from a replica graflex. The prop was used for cosplay and has minor scratches here and there, but it is otherwise in excellent condition.
Edit: Ive had some questions about whether this can be disassembled. It turns out the lower half is a solid piece. The upper have has some corrosion inside. Im starting to suspect it may be half of a real graflex but I cannot guarantee that. One of the red buttons is clearly a replica.
The other, original button does appear to screw off. The contact in the center of the top is spring loaded.
