Help indentifying propeller

[grahamrl]

I have recently stumbled across an old wodden prop that is 1.8 m in length, it has straight tips and one central hole with a metal mounting bracket. To be honest, I don't even know if it from a plane. It might be an old fan from a piece of machinery perhaps??

It's not from an aircraft. I think it's most likely from a wind generator of some kind.

Thought that might be the case.
