The Thornton-Pickard Rubyette No.1 is a British-made plate camera from the early 20th century, produced by the Manchester-based Thornton-Pickard Manufacturing Co. It was positioned within the firm's range of compact folding plate cameras intended for amateur and field use.

Public auction data for the Rubyette No.1 is extremely thin: the only recorded UK saleroom result we have is a single hammer price of £376 at Christie's in 2002, so any sense of what one is worth today must be drawn from that lone data point. With no recent comparables, the price a clean example sells for in the current market is difficult to establish with confidence, and condition, completeness of the original case and plate holders, and shutter function would all materially affect value.
