The Rouch Sliding Box Stereo is a wooden sliding-box plate camera built for stereoscopic photography, a body type associated with the early decades of British camera making. Cameras of this configuration produced paired images on a single plate for viewing in a stereo viewer, and were sold to amateur and professional users working with wet or dry plates.

Sales evidence for the Rouch Sliding Box Stereo is extremely thin, so any view on what one is worth today rests on a single data point. A Christie's UK auction recorded a hammer result of £2,760 in January 1998, which sits at saleroom (wholesale) level rather than dealer retail. With no recent comparable hammer prices, the current market value is unclear and condition, completeness of the original lenses, and provenance would heavily influence what an example sells for.
