This plug would have been placed in the Lunar Module COAS at launch to protect the electrical connection during landing, lunar exploration, and rendezvous with the Command Module. Accompanied by a certificate of authenticity from Dave Scott which reads, in part: “I hereby certify that the Lunar Module COAS mounting bracket electrical plug included with this letter was carried on board the Lunar Module ‘Falcon’ during Apollo 15…This electrical plug was stowed in the Lunar Module (LM) COAS mounting bracket at launch and subsequently extracted and stowed in the LM during landing, lunar surface exploration, and rendezvous with the Command Module (CM). The purpose of the plug was to protect the COAS electrical connection from moisture or debris until the COAS was installed…The plug was inserted into the LM COAS mount prior to launch, and then during LM activation was extracted and replaced by the COAS for various mission operations. The plug was then stowed in the LM during lunar landing, surface activities, and subsequent rendezvous with the Command Module, after which it was transferred to the CM for return to Earth as a memento of lunar surface exploration…This LM COAS Mounting Bracket Electrical Plug has been in my personal collection since returning to Earth.” In fine condition.
