Being offered is a Very Rare Accessory for the NASA Nikon F3 "Small" 35mm film camera.  Only 50 of these cameras were made by Nikon for use on the Space Shuttle.    For sale is a official battery Pack for one of these cameras!    Perhaps flown in space, but with no documentation. 

This Battery Pack has the NASA Space Shuttle Identification number SED33101573-301.  The serial number will be different than the one listed. 

The NASA Nikon F3 motor drive runs on a specially designed battery pack made of metal.  It operates on eight standard AA batteries which fit in the all-metal pack and connection is made through gold connectors on the end. Four screws on the battery  pack end seal the case, and need to be removed to open interior.
