The design for this water pistol is based on the first season Lost in Space laser pistol, but due to copyright issues with the show's producer, Irwin Allen, these pistols were never released to the public with a direct tie-in to the series. Later, after the word "Lost" was eliminated from the raised relief wording on the side of the gun, the toy was released as a generic "Laser Water Pistol." What makes the gun particularly interesting is that the words "In Space" were not removed from the side of the gun. They remain as a marker of the gun's origins. left. .
