Up for sale is a complete, highly collectible, and fully functional vintage Universal Propeller Protractor (Model 36D2844). This precision aviation maintenance tool was manufactured as official military surplus equipment, used to accurately measure/set aircraft propeller blade pitch angles and check control surface alignments.
This is a complete estate-find kit with fantastic historical provenance that you rarely find intact.
Key Features & Details:
• Official Model: Stamped 36D2844 directly on the reverse aluminum base plate.
• Military Provenance: Features its original, intact U.S. Department of the Army Calibration Label (DA Label 80) on the back, documenting its service history with calibration dates from 1988 to 1991.
• Vintage Character: The back plate features authentic, hand-engraved aviation station markings including \"DCA\" and cursive \"Propeller\" etchings.
• Complete Kit: Includes the original rear-mounted wooden alignment handle.
• Original Wooden Storage Case: Comes in its original finger-jointed wooden box. The interior features custom-cut wood blocks that perfectly cradle the circular tool, and the lid still retains the original internal clearance pads for the handle. Features a classic brass chest-style carrying handle and front hook latch.
• Condition Notes: The center dial turns smoothly and the vernier scale is crisp and highly legible. Both integrated spirit level vials (bubble levels) are completely intact with no cracks or leaks. The aluminum has a beautiful, authentic patina.
Perfect for warbird restorers, aviation mechanics, experimental aircraft builders, or military tool collectors.
