Gaumont had a fine wooden stereo camera in the market when it won the Grand Prix at the Expo of Paris in 1900. "Grand Prix 1900" was imprinted on the front plate of later Gaumont stereo cameras like the Stéréospido "Gaumont" of the 1920s, a sophisticated rigid body stereo camera for twelve 6×13cm film plates in an Elgé magazine back. It was equipped with a stereo shutter of the famous French shutter maker Decaux, with speeds up to 1/120 sec. . A similar model was made for 8×16cm plates. Synchronous focusing of the two lenses was possible, on the 8×16 version from 1.5 metres to infinity. The distance scale was imprinted on the bar that connected both lenses for synchronous focusing. The camera was equipped with two collapsible Newton finders, one on top and one on a side, both with crosshairs on the lens. Ground glass focusing was also possible. Therefore the plate magazine had to be removed.

The camera was available with different lens pairs, each made by one of the best lens makers:

for the 6×13 camera:

for the 8×16 camera:

The camera was marketed as "appareil stéréo-panoramique", the version with Olor Berthiot lenses as "non panoramique". On its top was a sign saying "L. Gaumont & Cie. - Ingénieurs-Constructeurs - Grand Prix 1900 - Paris". A wooden and a metal version were made.
