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 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.
