Stereo viewer dark mahogany is unknown brand (presumably D. Brewster, but is not marked). Suitable for 7 x 14 cm. The display was made around 1880. The viewer is in good condition with clear lenses, and the mirror is of good quality. The ground glass is intact and well transmits light. Wood has a small crack at the top of the mirror. It is certainly a good viewer to use, but also a beauty to showcase. Measures Viewer / Glass 7,5x13,5
