Group of Optical and Electrostatic Scientific Laboratory Apparatus, 19th/20th Century,
Including a brass concave mirror on an adjustable stand for light and reflection demonstrations; a long black optical bar equipped with multiple small lenses or mirrors, used to illustrate optical principles; a smaller wooden ebonized tripod stand inscribed in gold letters "Max Kohl, Chemnitz.", possibly for lenses or other components; a brass discharge rod; and a round framed plate that may serve as a base for an electrophorus or a dielectric component and a glass lantern slide of mirrors on stands. The slide is inscribed, in part, "from the Geo III Collection at Kings College London". These instruments reflect the typical construction using brass, ebonized wood, and steel, common for scientific apparatus of the era.

Largest Dimensions: H: 18 1/2 x W: 12 x D: 12 in. General grime and wear throughout. Magic lantern slide is cracked in four places, 4, 2 1/2, 2 and 2 3/4 in.
