Default propeller ID help

I have a mahogany propeller that is 9'-6" long with copper/brass ends. It has 8 1/2" holes drilled in hub with 738 FCH stampings on hub. Can anyone help with identification and/or value. I have been told it may be off a curtiss navy flying boat from world war1. Any information would be appreciated. Thank you

I think it's very likely from a Navy flying boat or a similar aircraft, but I don't recognize the stampings, other than the "FCH" and I still don't know what that stands for. Are there any other numbers stamped on it?

Its size and appearance look consistent with a Liberty engine in a tractor application. You can tell that it's not from a Liberty engine if the hub dimensions don't match it on this chart.

Lots of these style propellers were sold off as surplus in the 1920s.

My mistake, letters stamped on hub are"FCR" not "FCH"! Thanks for the charts my prop matches specs exactly for the Liberty 12 engine.
