Newman & Guardia Special Sibyl

The Newman & Guardia Special Sibyl is a British-made folding plate camera from the early twentieth century, produced for advanced amateur and professional use on small-format glass plates and cut film.

Sales data for the Special Sibyl is thin: a single recorded UK auction hammer result from April 2022 sold for £188, which sets the only firm reference point for what the camera is worth at saleroom level today. With just one wholesale data point, the figure should be treated as indicative rather than a reliable median, and condition, completeness of plate holders, and shutter function will materially shift the price either side of that mark in 2026.
