You are bidding on a FANTASTIC example of a WW2 US Navy MARK IV Drift Sight!  This was used in various Bomber and Reconnaissance aircraft, such as the B-24, B-25, PBY Catalina, and others!

Drift gauges had various functions for navigation (course corrections based on wind speed and direction) and bombing (standard and parachute).  They were also used for flight testing, systems calibration, and weather monitoring.

The Mark VII Drift Sight 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 Sight 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.  Made by Keuffel & Esser, the data plate still remains, and is clearly legible!  Manufactured pre-1945, it was used during the war.  Works in conjunction with a Gyroscope, with is interesting.  Optics are very dirty and will need cleaning.  Measures around 5 feet long.  Would make a SUPERB addition to any collection or display!

Please note that the shipping cost is an estimate.  It will be calculated more accurately based on the buyer’s location.

——————- 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. I will describe each auction to the best of my knowledge and take as many photos necessary to ensure you are pleased upon receiving your item. All sales are final, so please make sure your questions are answered to your satisfaction before you purchase. 

——————- ABOUT ME —————– 

Although my passion is the Me109, I do offer many other German Aircraft (Fw190, Me262, etc.), as well as USAF and Japanese items. Occasionally I do offer many non-vintage items such as prints and art relating to the time period. As a private collector myself, I am constantly on the lookout for historical memorabilia, authentic photographs, artwork or anything unique relating to military aircraft.
