If set up vertically, it becomes a digital microscope.

The thread on microscope objectives is pretty standard, old DIN designation.
Pentax has an M-series microscope adapter with the same thread. Mounts
straight on a bellows or a camera.
If you have any 4X to 10X laying about, it would be fun to test. According
to Web sources, the most suitable ones have an infinity symbol engraved
along with the magnification description. Apparently they can be mounted in
front of ordinary photographic lenses for more magnification and enabling of
camera electronics.

Mike,
the X4 indeed an objective lens.
Wild Heerbrugg was a Swiss optical instruments manufacturer.
The microscope it came from is pictured here:

Note the spotlights above the tray. The 4X is probably included to
have
the instrument double as a stereo loupe for biological specimens.

Interesting design. Not stereo, despite the description, without
double
objectives. I wonder what its original purpose was.
How did you mount the objective? I have access to a vast
selection...... 8-)
