The Rover detective camera was made by J. Lancaster & Son of Birmingham from 1890 and was supplied in a leather case for disguise. Nicely made of polished mahogany it is fitted with a brass Lancaster lens and their Patent See Saw shutter. Twelve ¼-plates in narrow frames are held in a top section and then dropped into place by a side lever.
