Bomb Sight Type D-8, US Army Air Force, for Parts or Repair (BOMB2)
This is a partial sighting head to the early WWII-era bomb sight type D-8 used by the US Army Air Corps/Force early in the war. These are rare to find, even in this condition. They were soon outdated by the Norden and Sperry bomb sights.
