Flown altimeter cover carried on board the command module during the Apollo 9 mission. Aluminum cover measures approximatelty 2.75″ in diameter, with a pull ring affixed to the front, and a small square of Velcro affixed to the reverse. Part is numbered “SEB 33100063-302 S/N l006,” and is signed on the front in black felt tip, “Jim McDivitt, Flown on Apollo 9.” Accompanied by a certificate of authenticity signed by McDivitt, a photo of McDivitt holding the cover after signing, a photo of the control console showing the altimeter (with a corresponding square of Velcro) at the top, and another composite photo of the console, again showing the altimeter. The Altimeter in the Apollo CM (panel l-A) indicates pressure altitude of the command module up to 60,000 feet, therefore it was only used by the crew during the early stages of initial powered ascent and then again at the very end of the mission. The altimeter is monitored to verify deployment of drogue and main parachutes at proper altitude. An adjustable marker on the dial is set prior to launch and is used as reference for manual deployment of main parachutes during an abort below approximately 10,000 feet. For the rest of the mission the altimeter was typically covered by this aluminum stopper. Flown, astronaut–certified items are always in supremely high demand.
