Starfleet Tricorder from Episode, "Arena" of Star Trek: The Original Series (Paramount TV, 1967).

Vintage original Tricorder (portable sensing-recording-computing device) prop constructed of fiberglass resin, vacuum-formed plastic, aluminum, wood and vinyl components. This hand prop was built by the Desilu/Paramount prop shop and features a flip-top panel containing an aluminum-framed 2" x 1.5" plastic view screen, a faux speaker screen, 3-sphere pins with 3-faux knobs mounted beneath. The front of the device features 2-front panels with aluminum pulls. The short panel is fixed shut, and the lower larger panel hinges at the bottom to reveal an empty interior. Of particular note, the aluminum bar at the top of the opened panel reveals scorching from the smoke bomb used in the scene in the Season 1 episode "Arena" where the device overloads on Spock (Leonard Nimoy) and he tosses it away. Includes the original integral faux leather carrying strap (Note: An unfinished leather strap with brown suede exposed on one side was installed on this Tricorder for "Arena". Production later switched to the present faux leather strap design that is finished on both sides). The prop measures 5.5" x 7" x 1.75" and exhibits age, production distress including scattered scratches and scuffing. Comes with a COA from Heritage Auctions. From the Collection of Greg Jein.
