Antique brass 16" fan blade, Not sure of manufacturer. measures 16 1/8" tip to tip, center hole is 5/16" but looks like it has a reducing insert in it, set screw included, center hub is 13/16" dia. reduced to 9/16" at the end. A couple of the blades have a little bend, I will say looking at this it DOES need some straightening and possible balancing for use.
