This is a pair of field glasses that allow the panel holding the field lenses to be swung open and dark-slides inserted in their place and the replacement of the eye-pieces by photographic lenses. When used as a camera the disguise was lost as the 'eye-piece' was then towards the subject. A year or two after its introduction a cheaper lens - the Lynkinoscope - was offered, this reduced the price from £15 to £10. The optical arrangement when used as a field glass is a Galilean form common at the time.
