It is a 4 blade propeller and is made of all aluminum. It is in fairly rough condition and definitely is showing some battle scars as you can see. The Propeller measured from the center sitting flat to the top measures 2 5/16 tall.It measures across from blade tip to blade tip about 8 wide. The bottom of the propeller (flat side) measures 3 7/8 across. The 2 small mounting holes are about 5/16 and have no threads in them.
Looks like these holes accepted mounting studs and bottom out at about 1/2 deep. Hole spacing is 3 5/16 center to center. As you can see on the back side it looks like the propeller was threaded on due to the threads cut in the back side of the propeller. It also has 4 holes threaded for set screws around the outside body. The back side of the propeller is about 1 3/4 deep.
A really neat collectible original piece. Would look excellent in any collection!
The part #s on the back of the propeller are, serial # (5574), (HT 458) and (1473465-K). The propeller has the word Michigan on it also.
