I'm guessing that it's probably from a Curtiss H16 flying boat. The size is about right. I think the "P.P." is most likely for Paragon Propeller (the War Department assigned those letters to Paragon). Check the hub dimensions, then go to this page (http://www.woodenpropeller.com/Hubmeasure.html) and follow the link to the table of hub dimensions. It should fit a Liberty engine.

I've got one that I haven't yet photographed, but will try to do so. It has a more or less "diamond" shape to the blade, i.e. narrow at the tips and hub, widest at the middle, with straight edges in between.
