A fine example of this late 19th century laryngoscope which would use an oil lamp for its light source.

The apparatus would attach around the glass chimney of the oil lamp. The light would be focussed through the lens onto a reflecting mirror on one side, counterbalanced with a weight on the other . The operator would look through a hole in this mirror so that his line of vision would be parallel to the plane of light which would illuminate the pharynx and larynx. The instrument marked Pat June 86 is made by Lentz & Sons is complete in its original box with instructions.
