The Thornton-Pickard Ruby Speed Camera is a British-made plate camera fitted with a focal-plane shutter, produced by the Manchester-based Thornton-Pickard Manufacturing Company in the early twentieth century. It was positioned as a higher-specification press and reportage instrument capable of fast shutter speeds beyond what most conventional shutters of the era offered.

Auction-hammer results for the Ruby Speed Camera are scarce, with only two recorded UK saleroom results: £4,500 in 2017 and £6,000 in 2014, giving a midpoint around £5,300. With so few data points, what a Ruby Speed Camera is worth today depends heavily on completeness, originality of the focal-plane shutter, and the lens fitted, and individual examples can sell for substantially more or less than this range at auction.
