Help with an old prop?

[hock]

Can anyone give me an insight into what this prop may be from? (or dates etc?)

There are no markings at all that I can distinguish, but with the size and shape I would imagine its from an older/larger aircraft?

Its approximately 5 feet top to bottom

Thanks for any help

Anyone any ideas?

I regret, none from me.
