You are bidding on aVERY NICE original WW2 German Luftwaffe Aircraft Fuel Pump and Pressure Regulator Assembly (8-4605 A-2)! Manufactured byDBU (Deutsche Benzinuhren), Berlin, and driven by aSiemens Apparate- und Maschinenbau electric motor.The Luftwaffe Libellen were precision spirit levels used to ensure correct horizontal alignment of aircraft weapons and aiming systems during installation, calibration, and maintenance. The Fl.62016 libelle was used in conjunction with aiming and alignment equipment such as the Fl.62000 Zielenprüfer 5B series, allowing accurate leveling during ground setup of aircraft armament and sighting systems. Used specifically with 20mm cannons.Made of aluminum and steel, this item is in VERY NICE used condition! It remains complete as the individual component, with intact glass vial and clear fluid visible in reference photos. Showing only light handling wear consistent with wartime service. No cracks or repairs observed. I have shown its location in the last photos. A scarce and desirable original Luftwaffe aiming system component, correctly offered as a standalone part for advanced aviation or instrument collections!
