Scope and content
Item is a wooden and brass stereoscope with wooden hood cover. This object was used to view two nearly identical photographs, or stereographs, as one three dimensional image. The stereograph would be placed in the sliding card holder and adjusted to fit the user's vision until the two images overlap to mimic a three-dimensional effect. Item is a box type viewer which folds into it's own storage case. Additional reflector can be placed in adjustable brass arms to illuminate transparencies with its white or mirrored side. Viewer is mounted on underside of the lid case. Once inverted and lowered into the box the base becomes the the cover. Lock on either side designed to hold object in place. Later versions of this object included storage units for both viewer and slides. Such as a vertical model able to adjust the viewer to a convenient height and a horizontal cabinet to house stereoviews.
Written on lenses: Achromatic Smith Beck & Beck; Stereoscope 31 Cornell London.
