WW2 US Army Airforce Aircraft TYPE B5 DRIFT METER B-17 B-24 B-25 NICE

This was used in various Bomber and Reconnaissance aircraft! Drift gauges had various functions for navigation (course corrections based on wind speed and direction) and bombing (standard and parachute). Hey 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. Made of brass, aluminum and steel, this Drift Meter is in EXCELLENT used condition! Some slight marks and wear due to the age, but VERY solid, and appears to be 100% mechanically functional! All knobs and dials rotate and adjust as they should… The disk that goes on the right side is missing should be easy to replace. Made by AGFA, the data plate still remains, and is clearly legible! Manufactured pre-1945, the optics are NEAR PERFECT, with no spotting or haziness! Rubber has hardedend over time. I have shown its location in the last photos. Ke a SUPERB addition to any collection or display! TERMS OF SALE. Most of my items are vintage, and as such are AS-IS, so you must therefore expect a degree of wear due to age and/or usage. ABOUT ME.
