A prop thumb used by Lore (Brent Spiner) in the Star Trek: The Next Generation episode "Brothers". In the fourth season episode, when doctor Soong accidentally implants an emotions chip into Lore, he opens his thumbs fingernail to activate a emergency transporter to escape capture by the crew of the Enterprise. The thumb is made of a inner layer of fiberglass and is covered in a rubber "skin" painted Data's signature gold color. The fingernail of the prop thumb flips up revealing a small button that activates a LED. Item is powered by a 9v battery that is hidden inside the thumb and concealed when the thumb is worn by the actor. Item shows signs of wear from production use and storage over the years but remains in excellent condition, and the electronics have been tested and are in perfect working condition.
