Good working condition:

-head mounting screw

-quadruple nosepiece turret

-sample stage with finger slider and clip: a bit tight on the Y direction control but very manageable

-condenser carrier with working pinion-rack system

-coarse and fine focus block

-power on, lights up and intensity adjustment smoothly, 120V 20W tungsten bulb

Overall it’s a very good body and power base. Just needs optics to complete a classic Olympus CH microscope.
