Presented below are some detailed photos of a screen used Anabolic Protoplaser medical instrument that was originally painted red and used in Dr. McCoy's sickbay during various episodes of TOS; and then painted black and re-employed in the filming of Star Trek: The Motion Picture (1979). In the screenshots following the modern-day images, this prop can be seen on the table of surgical instruments beside Nurse Chapel in the 2nd season TOS episode "Journey To Babel" (first airdate: Nov. 17, 1967) and is seen being used by Chapel on Spock in the sickbay scenes from ST:TMP. A rare prop with a history of service in The Original Series and the feature film incarnation of Star Trek.
Many thanks to long time Star Trek fan and collector Paolo in Italy for his kind permission to display these photos.
