Brough Superior (Lawrence of Arabia)

[Smittie61984]

I have a history project thingy where we had to pick a historical movie and write about something within the movie that may be inaccurate or just interesting. Such as say in a Vietnam movie having soldiers use a current generation M16 vs using a 1st generation M16.

I picked Lawrence of Arabia because I knew of the motorcycle scene and that T.E. Lawrence was a motorcycle enthusiast. Specifically with the Brough Superiors.

Now being that they made the movie in the early 60s and Brough quit making their bikes in the early 1940s I'm guessing that no one in hell would actually crash/lay down a real Brough Superior (if they did they should be slowly tortured to death) which they did in the movie. I figured they tried to replicate the bike with another brand of bike. I think they did that in a Tom Cruise movie by dressing a KTM up as a Ducati Hypermotard.

Does anyone know what actual bike they used in the movie?

Here is the scene:

I can tell the exhaust is different from Lawrence's actual bike but that's about it. I was hoping to get a look at the brakes too because the real Broughs had an odd brake lever set up. Though they may have used a real for the beginning and then a fake for the wreck/jump.

His actual bike (that he wrecked):

Appreciate any help.
