Anyone recognize what lens this is?

Yes its off of an old Leica rangefinder camera.
Its a Leitz Wetzlar.
Its attached to the camera with a Leica to Nikon adaptor.

I stand corrected its a Leica to Canon adaptor. Don't know what I was
thinking.

Google isn't much help:
http://images.google.com/images?ndsp=21&q=leitz+wetzlar

Is that an optical converter/adapter to make a rangefinder lens work on
the DSLR? Either that or it's some kind of medium format or bellows lens
but others by that name seem to be rangefinders or microscopes...

Oh, in the same folder there is another pictu

The "OUAGO" in the file name apparently refers to some kind of
teleconverter or focusing helix...

The "Leica M-EOS" indicates a Leica M mount to Canon EF mount converter.
This would have to have optical element(s) since the flange distance of the
former is much shorter than the latter.

The "OUAGO" item looks to be converting Leica M39 screw mount to some
bayonet with focusing, and the item on the left looks to be another
focuser.

Appears to be closely related to this::

What is the context, Alan?

The last link explains the Visoflex SLR adaptation of some sort,
for Leica lenses (roughly translated):

So this is apparently two glass 'teleconverters' attached to a pre-leica
lens to make them focus on a 35mm DSLR?

Visoflex lenses will infinity focus on a dSLR body without extra optics as
the Visoflex unit added a couple of inches to the Leica body. To use those
lenses on a body with out the Visoflex relex unit they were mounted on a
spacer tube like an extension tube, designed for that lens.

I doubt that the Leica Visoflex to Canon EOS adapter has any optical
elements in it.
Leica produced special long register distance lenses which could only be
focused via the use of a Visoflex on a Leica RF camera.
The Visoflex is a reflex housing which attaches to the front of a Leica
RF camera (there were versions for both M39 and M bayonet) and turns it
into a clunky SLR camera.
The registration (mount to film plane) distance for the Visoflex is much
greater than the registration distance for EOS.
