Witch tree?

The guy driving the little train through Kew Gardens in London didn't know which tree is the tree used in the Harry Potter movies as the whomping willow.
He just knows it was one of the massive trees in the area.

Too many branches

I supposed the Kew Gardens people felt if they identified the tree, the Gardens would be overrun by Potter groupies looking to take a selfie by the famous tree taken to slamming anyone who came too close.
So Marc and I just tried to guess and take photos of the most likely candidates.
A couple of problems arose: there are LOTS of trees in the gardens that have big, twisted trunks and several that look just like what I can remember from the movies.
The other problem is that the tree changes from movie to movie.
Sometimes it has big, clubby branches that it flings around trying to keep snoopy kids away.
Other times it's dark and still.
It's always a really big tree with dark bark.
Here's a few that I think qualify to be the one:

Too plump at the bottom

Too gnarly

Is this it? I like this one.

You tell me.
