    Very nice picture. Martin Taylor, owner.

  2. I recall that this engine had a piston of two different diameters as shown in the second smaller photo. This enabled a greater swept volume to enter the crankcase resulting in a larger charge into the compression chamber thus increasing the power.
    Post 2nd war there was an EMC (Elrich?) motor cycle produced with slave cylinder in front of the power cylinder and connected to it by a con rod to the main con rod. I think it was a 350 cc.
