The Thornton-Pickard Filmak is a folding camera produced by Thornton-Pickard Manufacturing Co., a British camera maker active in the late 19th and early 20th centuries. It belongs to the era of folding plate and roll-film cameras, a body type common before the rise of compact 35mm equipment.

Evidence of what a Filmak is worth at saleroom level is limited: a single recorded UK auction hammer result from 2017 sold for £42, so the price reference point is narrow. As of today in 2026 there is not enough recent data to establish a reliable median or range, and values for any given example will sell for sums driven primarily by cosmetic condition, completeness of the bellows and shutter, and bidder interest on the day.
