WW2 US Army Airforce Aircraft TYPE B5 DRIFT METER B-17 B-24 B-25 -very clean
Sharp optics , rubber is still soft! Hard to find a cleaner one! They were also used for flight testing, systems calibration, and weather monitoring. The B-5 drift meter is used to measure the angle between the heading of the aircraft and its actual path over the ground, thus used to correct the course of the aircraft. The instrument’s viewing port projects from the side of the aircraft. When viewing the ground through the eyepiece while in flight, the navigator observes the travel of fixed objects across the lens. With a pencil mounted in the receptacle on the movable arm, these objects are tracked across the lens and their path transferred in pencil to the recording pad manually by the navigator. Once done, the drift angle is determined and course correction calculated and communicated to the pilot.
