The Gaumont Stereo (Spido, metallic) is an early stereo plate camera, part of Gaumont's Spido line of metal-bodied folding stereo cameras intended for paired-image photography on glass plates.

At UK auction, a hammer result of £100 was recorded in January 2024, which is the only verified data point currently on file, so any sense of what one is worth today rests on that single saleroom figure rather than a true range. Buyers asking how much a Gaumont Stereo (Spido, metallic) sells for should treat this as indicative only, since condition, completeness of the plate holders, and shutter function can move the price materially in either direction.
