I believe this is a foreign-made propeller for a paramotor. It was found at my grandfather's house. It has been opened but not used. The condition is good, but I cannot guarantee it can be actually installed and used. It's probably several decades old. The newspaper used as packing material is foreign, so I assume it's made overseas. The box is dirty. Brand is unknown. Total length: approximately 137.0cm Center diameter: approximately 11.2cm Thickness of the center part: approximately 4.4cm Diameter of the 4 holes: approximately 8mm Center hole diameter: approximately 2.5cm These dimensions were measured by an amateur. There may be some errors. It will be shipped in the outer box shown in the photos. Please feel free to ask any questions you may have, and I will answer to the best of my ability. I had several of these, but this is the last one. I think it would be nice to display it as an antique. Thank you for looking.
