The Chadwick (W.I.) Tailboard camera is a 19th-century British wooden plate camera of the tailboard pattern, in which the rear standard is fixed and the front standard racks forward along a hinged baseboard. Cameras of this type were sold for studio and field use during the wet-plate and dry-plate eras.

With only a single recorded UK auction result to draw on, the Chadwick (W.I.) Tailboard hammered at £288 in 2017 — a wholesale saleroom figure rather than a retail price. On that limited evidence, similar Chadwick tailboards today tend to trade in the low-to-mid hundreds when offered at auction, with condition of the bellows, woodwork and brass fittings being the main driver of what one is worth.
