The Meagher Tailboard Stereo Camera (double extension) is a 19th-century British wooden field camera built for stereoscopic photography, using a tailboard folding design with a double-extension bellows for additional focusing range. Cameras of this pattern were intended for use with paired lenses to expose two side-by-side images on a single plate.

Auction data for this model is thin: a single recorded UK saleroom result from 2017 hammered at £300, so the available reference point for what one sells for today is a single data point rather than a range. As a hammer price it reflects wholesale auction level rather than a retail or dealer asking value, and condition of the woodwork, bellows and brass fittings will swing what any given example is worth.
