Foldable Stereoscope ‘Kilburn viewing case’

William Edward Kil­burn designed a view­ing case for stereo daguerreo­types, which was reg­is­tered in Britain and patent­ed in France in 1853. The view­ing case was exclu­sive­ly man­u­fac­tured by Moran and Quin in Lon­don and sold to daguerreo­typ­ists who could cus­tomise it with their own names.
