This is the AMT / Ertl 22″ Special Edition Lights and Sound 1701-A. I made a custom base with part of the stock base in the kit. It’s hand painted, and the Nacelle Grills, Impulse Engine Grills, Turbo Shaft Blue Dome, Photon Torpedo Tubes are made from scratch without any aftermarket replacement parts. And all the windows are resin filled. (I was on a strict budget) And an upgraded lighting system with 30 LEDs and 4 CCFLs powered by a 12 volt adapter. I also used the Photon Torpedo & Phaser Sound Effects with a plaque mounted over the speaker.
