value for family treasure

[bevo1916]

I have inherited a prop from what I believe was a 1916 Curtis SE5, 6 cyl. inline. My grandfather was an instructor in Army Air Corps at Chanute Field in 1915-1916. After he was sent home on medical following a crash in 1916 his fellow instructors shipped the prop from the plane home to him. It's been in family ever since. It's in excellent condition with his name, rank, insigna and field painted on left side. I'd like an idea of value for insurance as it's hanging on wall of my family room. I also have pictures of him in service there as well as of the plane and crash site.
Numbers stamped into wood on front either side of hub: SC11439; 8-4D-5-OP; 441; also a shamrock shape and #1 on one side and OX5 and #2 on the other.
Can anyone help me with value estimate.

"Market" value would depend largely on its condition, and I'm sure that's going to be less than its value to you as an heirloom. I think you should check with your insurance company first to see how THEY determine value for it in the event of a loss. You may find that there's a limit to the amount they'll pay out.

I'm not sure about the Curtiss SE5 in 1916, and would seriously question that history. The SE5 used a 200 HP engine and the OX5 is about half that. I know there was an order for Curtiss to build 1000 of them during the war, but to my knowledge, because of the end of the war only one was ever built, and I'm not sure what engine powered it.
