The Chadburn Sliding Box is a British wet-plate-era wooden sliding-box camera, a body type used in the mid-19th century where focus is achieved by sliding one box inside another. Chadburn was a Sheffield-based optical and instrument maker, and cameras of this construction were typical of the early commercial photographic equipment sold in Britain at that time.

With only a single recorded UK auction hammer result, market data for the Chadburn Sliding Box is thin: one example sold for £763 at Christie's in 2001, which remains the only verified saleroom price on record. As of today, anyone trying to work out what a Chadburn Sliding Box is worth in 2026 should treat that figure as a historic data point rather than a reliable guide to current value, since condition, completeness of the original lens and plate holders, and provenance dominate what these early wooden cameras sell for at auction.
