The Gaumont Stereo Spido Ordinaire is an early 20th-century French stereoscopic plate camera, built for paired exposures on glass plates to produce stereo image pairs. It was sold as part of Gaumont's Spido line of folding and box-form plate cameras aimed at amateur and advanced amateur users of the period.

Sales data for this model is extremely thin: a single UK auction hammer result from June 2020 sold for £500, and that figure is the only reliable reference point for what a Stereo Spido Ordinaire is worth at saleroom level today in 2026. Because hammer prices reflect wholesale auction levels rather than retail dealer asking prices, a clean, complete example with original plate holders could sell for more, while an incomplete or damaged body would likely fetch less.
