Two components for the Mars Viking Orbiter's solar arrays: one trapezoidal outboard hinge with a wired port for a motion sensor switch, measuring approximately 27″ x 10.25″ x 3″, marked on the underside, "10040069-1, S/N 005"; and one rectangular inboard latch, measuring 22″ x 8.25″ x 4.5″, marked on the underside, "10040068-2, S/N 007." In overall fine condition. Accompanied by an original JPL storage request receipt for the inboard latch, and by photocopied JPL inspection report paperwork related to the Viking's hinge and latch assemblies. Any Viking hardware is extremely rare, making this a great opportunity for collectors.
