Beautiful large Roswell type stereo-graphoscope or tabletop stereoscope from the mid nineteenth century. Most likely from France in the 1860s. Dark wood with inlaid wood edges. Graphoscope and stereoscope lenses panel is carved with scrolls and ebonized. Sides to the stereoscope fold up and fasten to the front. Back graphoscope panel has frosted glass and more scrolls with less detail in the carving.
Both panels fold down easily. Lid of device opens and allows for adjusted height. Prop to adjust height is stamped with a circle and star. Words read "Brevete SCDG." This stands for "brevete sans garantie du gouvernement," which means it was made without a patent. Napoleon Bonaparte coined this phrase on September 27, 1800, but it was required to be written on items without a patent after 1844.
Graphoscope lens is in good condition but separate from the panel. Stereoscope lenses have knob for focus, but knob does not adjust. All hardware to move and fasten the device in place are in working order, and it is possible to use this instrument with ease. The lid is slightly warped from back to front, but this does not affect use.
It measures 22 5/8 H x 11 7/8 W x 6 1/2" D when closed, and weighs 8 lbs. 6 oz.
