Star Control Assembly Short Sunderland but the pages inside appearThis 2 piece device is thought to be part of the MD 1 Astro Navigation System used in early B 52 bombers, but we cannot confirm this. It consists of a sighting mechanism that includes a mirrored lens, and a cover which probably affixed to another housing assembly. Measures ~ 11 inches x 5 inches.
