The Royalty is a field camera sold under the London & Paris Optic & Clock Co. name, a British retailer associated with wood-and-brass plate cameras from the late Victorian and Edwardian period. Cameras of this pattern were positioned as general-purpose outdoor plate cameras for amateur and professional use.

At UK auction in recent years, hammer prices for the Royalty field camera have ranged from around £150 to £380, with a median close to £220 — wholesale saleroom results rather than dealer retail. A January 2023 result at £150 sits at the lower end, while earlier Christie's sales reached £384 in 2005 and £223 in 2002, so what one is worth today depends heavily on completeness of the original fittings and the condition of the bellows and wood.
