Antique two blade boat propeller.  I believe it is brass but don't know for sure as we know very little about these. It is marked Michigan in the center hub. Selling as found, we didn't even wipe it off. Looks like to would polish up real nice. Selling very much as is, what you see in the pictures. From the estate of a 90 some year old fellow that had been collecting stuff since the 1940's. Watch for our auctions, lots more to come.
