This was purchased through the Profiles in History (PIH) auction 40 and is the 'working' phaser used by Wil Wheaton (and held by Patrick Stewart) in the episode 'The Final Mission' of Star Trek: The Next Generation. It is believed by PIH that this is a re-purposed 'Dummy' phaser (1 of 2) from Star Trek III: The Search for Spock. Electronics were added by production to the P1 and the handle was wrapped in light brown suede for use in the episode.A view of the 'working' P1 on the top of the P2.
