The model's name is written on a small plate where "Bté SGDG Paris" is also noted.
It is a stereoscopic camera with two lenses, both anastigmat 4.5/75 mm, manufactured by the Boyer brothers.
The shutter is an Ibso (Gauthier), which is strange considering that Brizet filed several patents for stereo shutters.

The model name is written on a small plate where "Bté SGDG Paris" is also noted.
The two lenses are anastigmat 4.5/75 mm with serial numbers 10034 and 10035, manufactured by the Boyer brothers.
The shutter is an IBSO (Gauthier) and provides the following speeds: B, T, 1, 2, 5, 10, 25, 50, 100.
The speed adjustment is done on one of the blocks, while the aperture is adjusted on the second. It would be interesting to see the coupling, probably hidden by the cover located between the two blocks.
