This is a model One-Sixty monocular microscope from American Optical. It is in good working condition but shows some wear to the exterior from previous use. It comes installed with three objective lenses, the 4x, 10x, and 43x. All objectives were able to focus properly on a subject. Sometimes the coarse focus knob feels a little loose, but the microscope is nonetheless able to focus properly.
The microscope shows visible wear to the exterior. No outside accessories are included.
