This is a sturdy brass instrument on a black iron base that was “designed to meet the demand for a high class spectrometer for use in college and technical laboratories.” The horizontal circle is 15 cm diameter, graduated on silver 1’ and read by verniers and microscopes to 20” of arc. A brass tag on this circle reads “WM. GAERTNER & CO. / MAKERS / CHICAGO.”
