The Watson Stereo Tailboard is a wooden tailboard-style stereo plate camera, a 19th-century field-camera design used to capture paired images for stereoscopic viewing. Tailboard cameras of this type were typically constructed in mahogany with brass fittings and folded flat for transport.

Sales data for the Watson Stereo Tailboard is extremely thin: a single recorded UK auction hammer result of £705 from 2001 is the only reference point, so a current market value or median cannot be reliably stated as of today. Condition of the bellows, woodwork and any original lenses or plate holders has a significant effect on what these wooden stereo cameras sell for at saleroom level, and a one-off result from over twenty years ago should be treated as indicative rather than a current price guide.
