The Underwood Tailboard Camera is a wooden field camera of the tailboard pattern, a body style produced in Britain during the late 19th and early 20th centuries for plate photography. Underwood, a Birmingham-based maker, supplied this kind of camera to amateur and professional plate photographers of the period.

Public auction data for this model is extremely thin: the only recorded UK saleroom hammer result is £126 at Christie's in 1998, which gives a single historical reference point rather than a current market value. With no recent comparables, what an Underwood Tailboard Camera is worth today depends heavily on completeness, the presence of original brass fittings and a lens, and overall woodwork condition, and individual examples can sell for materially more or less than that 1998 figure when they next appear at auction.
