Mmm....
evidently a Sopwith, very recognisable When I saw it on Sunday I thought the film editing guy had mixed up the closeup shots...but looking at it again he did indeed say the plane pic the owner was holding was a Sopwith when it's actually an FE2B
And then he looked at the one he himself was holding...
and said it was an FE2B when it's clearly not. My guess is that it's a Strutter.
To be fair to him he only said he'd seen a lot of propellors made in to stuff like hall stands and threads on cycling forums...I reckon he nipped over to the military guy Roy Butler, was told what they were, and then got muddled up during the filming.
