This is an original U.S. WWII aircraft load adjuster produced for the Lockheed PV-2 and PV-2C Harpoon, complete with its leather hard case and suspension hanger.

The U.S. Navy adopted a navalized version as the PV-1 Ventura, which entered combat in the Pacific during 1943. Lockheed subsequently developed the improved PV-2 Harpoon with a larger wing, increased fuel capacity, and other modifications intended to improve its performance as a maritime patrol and bombing aircraft.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe PV-2 and PV-2C load adjuster resembles a conventional slide rule but was designed to calculate aircraft loading and weight distribution. Using the adjustable scales and cursor, personnel could account for the locations and weights of crew, fuel, ammunition, bombs, and other equipment. This allowed the aircraft’s loaded center of gravity to be checked against its approved operating limits, an essential calculation for safe takeoff, flight, and landing.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe instrument is identified for use with:\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003ePV-2 \u0026amp; PV-2C\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eIt was manufactured by:\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e\u003cspan\u003eCOX \u0026amp; STEVENS AIRCRAFT CORPORATION\u003c\/span\u003e\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003e\u003cspan\u003eMINEOLA, NEW YORK\u003c\/span\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe load adjuster remains in excellent condition and shows very little evidence of use.
