This is one of 2 hero props that are powered by air and 12v. The third prop made for the movie was static. Compressed air makes the phaser banks rotate and the front firing tip moves. The phaser banks light up. I have the mounting bracket and other hardware not pictured as well. The other hero has been over restored and does things it didnt do in the movie when made but here is a you tube video of it because it really is cool! https://www.youtube.com/watch?v=9cpr5g4QdMY Having responded to a strange signal emanating from the planet ‘Kolarus III' near the Romulan Neutral Zone, “Captain Picard” (Patrick Stewart), “Lt. Cmdr. Data” (Brent Spiner), and “Commander Worf” (Michael Dorn) investigate. Riding the ‘ARGO’, an all terrain vehicle, they collect components of an android strikingly similar to Data, but trouble looms on the horizon as aliens native to planet give chase and Worf returns fire with this exciting prop cannon! Composed mainly of machined metal, this sturdy prop was intended for use on a vehicle mount, much of which is still present. A sliding bracket is fixed onto the cannon as is a rotating turret. The hand grips fold out from the cannon and lock into place, released by a switch for each, the right grip having an affixed thumb button for ‘firing’ the weapon, while the gunner keeps aim on his targets by the ‘screen’ at the end of the gun. The item measures approx. 28.75 X 10.5 inches, while the handles are deployed 29 inches, 11 when not.Having responded to a strange signal emanating from the planet ‘Kolarus III' near the Romulan Neutral Zone, “Captain Picard” (Patrick Stewart), “Lt.
