A 4 blade antique brass ship propeller is always a great find, especially if it is in brass.  This piece is solid brass and measures 24 inches in total diameter. And it measures 12 inches from the center of the hub to the edges of the blades. The hub is 3 inches in diameter, and 4 inches from front to back. This is a vintage brass propeller, pulled from a real ship. Both sides are photographed.  This authentic brass ship propeller weighs just under 37 pounds.
