In fine condition. Accompanied by a signed letter of provenance from retired NASA Subsystems Manager Robert Stuckey, in part: "Each Apollo and Skylab Command Module carried one Fire Extinguisher in case of an on-board fire. As NASA Subsystem Manager for the Fire Extinguishers, after each flight the Extinguishers were released to me for postflight testing of the extinguishing agent. In addition, I personally rendered each extinguisher safe for display by releasing all remaining pressure, and by removing the rupture disk and the bottom fill port plug…Attached is the burst disk, related hardware, and fill port plug from the Apollo 10 (CM 106) Fire Extinguisher, ID Number ME 280-0010-0003, SN 652570008 HHH."
