A very popular detective camera based on Miall's patent of 1889. It remained on sale until the early 1900s.

It is rather large as one changing box is filled as the other is emptied, so twice the space is used. Advertisements suggest that the camera, if wrapped in brown paper, would resemble a parcel of books. For purposes of disguise Fallowfield sold leather or canvas cases. The camera was advertised only in the quarter-plate size. Fitted with either a 5" Rapid Landscape or Rapid Rectilinear lens. The price was £5.5.0 in 1891.

Minor variations exist:

• Early models were optionally not fitted with a view-finder.
• Usually a single finder is fitted for landscape format. Some have a second for portrait format.
• A sheath is fitted to some models which covers the lens and finder openings, when the finder lid is raised the sheath is also raised.
• Leather covering was an option.

Later a focusing Facile was introduced this may have had a different mechanism as it took 12 plates or 24 cut-films without holders which could be exposed in any order. It was fitted with a shutter speeded 1 - 1/100, some advertisements say the shutter is by N&G.
