Fuel Quantity Indicator, PV-2 Harpoon, EA109-3 US Navy

Here is a Fuel Quantity Indicator as used in the US Navy Lockheed PV-2 Harpoon Patrol Bomber. It measured the fuel quantity in the two front center tanks and two rear center tanks. See photo of the location of the instrument on the co-pilot's side of the instrument panel from the Flight Manual dated 1946. Measures 3.25in diameter and ~4in deep. 

It is in reasonable condition given its age. The dial markings are clear and the glass and case are intact. The case is affixed by only one of four screws, and the internal wiring appears in need of repair, but cosmetically its an exceptional specimen.
