A complete silver plated otoscope or auroscope by Maw Son and Thompson set in its original box dating the late 19th century. These were used to examine the external auditory meatus and the tympanic membrane.
The mechanisms of illumination is ingenious. Early attempts to view dark receses were confounded by the light source obstructing the line of vision. Using a mirror to reflect light from an external source by 90 degrees, the central hole allows the examiner to look along the axis of the light. In mint condition with intact silver plating throughout. There is a similar example in the London Science Museum.
