exakta to leica screwmount adapter

[jean lafite]

does such a thing exist? i saw something on ebay that was five numbered rings that all fit together, but i wasn't so sure about it. does this set-up work? is that all there is, or is there something else, or is it all a waste of time. thanks for your help,

I was looking at that too, and am curious as well. The real question is, would it be rangefinder coupled?
