This is a hero Blaster, screen used throughout the first Star Wars prequal movie.
The blaster is made up of various components, including machined aluminium, rubber and solid plastics. It's quite large, and displays wonderfully. Parts of the Blaster resemble the later Stormtrooper blaster seen in the original trilogy, this was odviously the plan during the design stage.
The Naboo Guards can be clearly seen holding this style of blaster in many scenes.
The Blaster is in generally excellent condition, just minor scratches and rubbing as you'd expect from a prop over 10 years old now, and used heavily on set.
