Not sure which Curtis Aircraft this prop is from?

Thanks!

Could it possibly have been made foe a seaplane?

Most likely it was. The U.S. Navy was very active in the late teens and early twenties developing a whole line of flying boats, and experimenting with a variety of engines and airframes, which is why it is hard to know which combination of engine/airplane any propeller was manufactured for unless you have specific identity stamped on the propeller itself.

The "SE 364-572" is that specific identity, but the problem is that we don't have a listing of those numbers to reference it.

I'll try to see if those numbers match anything specific. It's half of a four-bladed assembly, and the "SE" prefix refers to "Steam Engineering", which was the U.S. Navy department responsible for procuring propellers at the end of WW1 and later.

I am not sure if this is from a Curtis HS-1 or a H-16 and wanted to get input from the "Wooden Propeller Community."

The propeller is 104" tip to tip.

Thanks!!!
