Playing with the Paramender

I found a paramender for my Mamiya C330 in the classifieds at RangefinderForum.  

The bellows on the C330 allows you to crank out the lens to within seven inches of the subject.  What you see is not what you get, however, unless you can crank up the camera parallel to the film plane so that the taking lens sees what came in through the top viewfinder lens.  That's the purpose of the paramender.
