Wow, great pics Evil.. Think I am starting to understand and get my head into the different 1 and 2 speed cranks.
Are you sure you didn't make a posting mistake with the pic you said is the 1 speed crank? it looks like the clutch side length is the same as the pic before. Hmmm.
Here is another couple of shots of my bad 1 speed crank that I am looking for.
