This viewer is made of polished wood.
The body has an opening where the stereo glass or paper photo is inserted
for viewing. The binocular eyepiece is focussed by a knob on the right. Their
interocular distance is fixed.
On the top of the body, a reflector is used to capture the light and project
it inside the body when viewing paper photos.
On the back side, a door supporting a glass can be open downwards to permit
viewing of glass stereo plates by transmitted light.
