American Optical Series-4 microscope for parts or build into working microscope.  The basic components are here, but would require a transformer to make the illuminator work.  It is in basic used condition and may benefit from lubrication, however everything moves and it would not be a priority.  All glass surfaces are free from dust, separation and fungus.  Included are a 10X objective, 43X objective, 10X eyepieces, Abbe Condenser with diffusion lens and a fixed stage plate.  These microscopes make great little work horses for veterinary applications, doctor's offices or hobbyist. Remember - it needs a transformer to operate the illumination system.
