Osborn Engineering Company Duplex steering

The joke back in the day was OEC stood for Odd Engineering Contraption, the company developed and patented the Duplex steering system shown here.  It was not a commercial success but it worked well enough that in August of 1930 the motorcycle, ridden by Joe Wright, achieved a world speed record of 137 mph with its big JAP V Twin. I wonder if normal rake and trail apply to this system. Apparently it liked going in a straight line but contemporary reports said it needed getting used to in regular use.
