A reader sent me this picture - it appears to be a Contax rangefinder (just like this one here) but with some additional buttons. The additional dial appears to be the same as in recent Canon DSLRs (see this Canon dial sticker). Maybe a photoshopped stock image?
The picture was published in the Outside magazine:

You can see it also on their website:
This is how the top of a film Contax G1 rangefinder looks like (source):
The top plate of a Contax G2 rangefinder can bee seen here.
