This has the Dash A after the serial number, indicating that this hub has been sent back to the manufacturer for upgrades and factory service. This is a strong and solid prop, with loads of life left in it. The variable pitch hub is actuated by centrifugal force, and allows for maximum power at take off, and efficiency at cruise.

It has been in use with Lycomings from 0295 and smaller and all cubs. These propellers were certified on most of the production airplanes during the big airplane boom right after WWII including Pipers, Stinsons, Ercoupes, T-crafts, Bellancas, Swifts, Aeroncas, Cessnas, Meyers, Monocoupes, Fairchilds, Grumman Widgeon, Johnson Rocket, Ryan Navions and plus some foreign airplanes.
The single-piece hub of chrome-nickel-moly steel retains blades flanges on large ball thrust bearings. A synchronizer gear between the blade flanges co-ordinates their movements. Adjustments for pitch range, balance and lubrication are all accessible externally. Blades for the Aeromatic are made of thin lamination of maple or birch bonded with thermal-setting resin to provide a structure stronger than a natural wood blade. AEROLOID plastic sheeting is pressure bonded to the exterior of the blade for protection against abrasion and moisture absorption. Monel leading edge tipping is applied over the AEROLOID plastic to protect the leading edge of the blades. Threaded ferrules are affixed to the blade butts by the standard lag screw method of blade retention. The threaded feature allows the blades to be removed from the hub without disassembly. The propeller is in good condition, with no dings. I will pay for shipping in the continental US, but anything else will be a different arrangement. I always ship insured
