APC/Paragon style. No decals. No bolt holes. ID ideas?

Hi all. My propeller contains the following 3 stamps:
8'-3"X5.00 Right Hand
4768
*1617*
The size and "right hand" stamp look like some of the American Propeller Co. or Paragon stamps I've seen on this site. However this prop does not have any decals nor does it have bolt holes.
Center bore diameter is 2 3/4"
I'm attaching photos. Any thoughts on it's maker? How common is it to have no bolt holes? Maybe it's a reject and never got drilled. One blade has a 10" crack and it has a chip out of one edge that looks like someone took a bite! Even with those flaws, I enjoy looking at it. Any insight is appreciated. Thanks.

Yes, most likely it was rejected late in the manufacturing process. It's even possible that it had decals which have since been removed.

I suspect that is is a Paragon.
