Vintage Olympus Research Microscope.
Good condition for its age.
The mechanicals seem to work well, and the light - at some point converted to halogen.
The lenses UNTESTED apart from a brief look through the X10 to check the light and condenser.
Lenses: all Olympus:
H1 100 1.30
PL40 .65 .17
NH20 .40 .17
PL10 .25
X4
I guess anyone deriously looking will work out the features from the photos.
COLLECTION ONLY so condition can be examined.
