Wasn't the bike ridden by TE Lawrence at the beginning of "Lawrence of Arabia" a JAP?

I thought it was a Brough Superior, but I might be mistaken.  Tony

It's a James A. Preswich (JAP) engine in a featherbed Norton frame.  Brough used JAP engines in some of their bikes, Matchless in others.

Indeed that bike is a nice piece of work, and thanks for posting the article from the UK magazine.

In my reading of TE Lawrence it would seam to me the sand would not make for a good enviroment for the open valve train i have seen on all JAP hotrod convershons of US. motors. The erley Brough Superior motors wour flatheads V Twins 900-12oo cc. That would work ok in the sand. the open valve gear is a speedway ie cinder track set up i think. Late model speedway JAP all inclosed changed post war??? I know you Gentelmen who have been overseas would know more about it than I any responce whould bee aprecataed Thanks in advance   Giant Jim

The First 200Mph 1/4 was done (in this country as far as I know) was done by Alf Hagon on a very similar V Twin although I think it was a Godden but still J.A.P. really
