The pillar supports the stage and the limb. The instrument is also fitted with an Abbe condenser and an iris diaphragm, features which were added later on. Based on the style and the low serial number, however, we believe that the microscope dates from about 1860. No carrying case or accessories. Signed on the tube: Oberhaeuser, Place Dauphine, Paris. Stamped on the bottom of the base: 2247.enBiologyFrench FirmsMicroscopyOptics
