Can anyone identify this prop?

Anyone have any information about this prop? Michigan Model # SSO-521-II-C

I am curious if it is a 20" or 21" pitch.

Thanks guys. Yea, I see where it's stamped 13x20. Wasn't sure if that means what I think it means I did a google search and some folks claim it as a 21p. I am also curious about the vintage. It does not appear to be a current product by Michigan Wheel.
