When found, the microscope lacked its original objectives. Two Hartnack objectives were added to complete the microscope. Schrauer microscopes were often supplied with lenses from this firm. Schrauer never made his own optics. Sometime in the early history of this microscope the substage was upgraded in a professional manner. Originally, the substage consisted of a screw-in adapter which held an aperture stop holder having three stops. This was converted to a focusing Abbe condenser which allowed the use four aperture stops below the lens of the condenser. The condenser was arranged to allow off-center movement of the apertures by rack and pinion in order to utilize oblique illumination.
Leopold Schrauer first began the manufacture of microscopes in Boston. By 1877, he was located in New York City at various addresses. Schrauer microscopes are relatively uncommon.
The tube of the microscope is engraved:
