Antique Holmes Stereoscope

Antique Holmes style stereoscope glasses. Made of wood, with glass magnifying lenses these made some photos look 3D! Likely made in the late 1800's. Pais is in good used condition, I believe it is missing a sliding bar with a clip to hold he stereograph. Bottom has metal bracket like pieces that are broken (see photos). Very nice display piece! Measures approx. 13" long, 6.5" wide, 3.25" tall.
