![]() There are two rounded jaws, one each to the right and left side with a tightening screw attached to one side so as to fit to different sized fingers. This is designed to hold and manipulate a human finger. Perhaps the most unusual feature of the microscope is the stage. The entire illuminator assembly moves with the optical tube as it is focused. Yellow and blue-green filters (latter broken) were enclosed with this instrument when it came to me. The illuminator has multiple optical elements and a window on the bottom accepts the filter holder, which in turn can accept different colored filters. The light socket is made of ceramic and sits in a centerable fitting with a three point centering mechanism, on point being sprung, the other two being knobs, similar to a modern condenser centering mechanism used to this day. ![]() The illuminator is supported by buttresses from the bottom which attach to the nosepiece, and two in the middle which attach to the upper midportion of the body tube. The Unusual cone-shaped objective is signed 'Ernst Leitz Wetzlar K 8x'. ![]() There is coarse focus by diagonal rack and pinion fine focus is via a lever on the nosepiece. A pair of curved supports in a crinkled black finish arise from the foot to join at the top with the pinion box and handle. The foot is rectangular and made of a nonmetallic material, possibly hard rubber. The microscope is a highly modified type.
