This magnificent GAUMONT SPIDO from 1898, made of wood covered in morocco leather, is over a hundred years old and is in an absolutely remarkable condition!

The speeds are marked from 0 to 5.
It is engraved 'Paris Congress 1889'.

The TESSAR ZEISS lens: f/6.3, 120mm under license from B. KRAUSS PARIS is in excellent condition.
The diaphragm is perfect and closes well according to the scale 40 - 50 - 1 - 2 - 4 - 8 - 16.
Helical focusing is achieved without any problem from 2 meters to infinity.

The two-part retractable optical sight with a mobile verticality indicator is in perfect condition.

Horizontal and vertical adjustments, with tightening levers, work perfectly.

A storage unit for 12 retractable plaques is attached to it.
The 12 metal plate doors are present, but I didn't understand how the concealment mechanism works.
The automatic view counter works.
The sliding wooden panel that allows for the safe removal of the store needs to be repaired.

A frosted, grid-patterned frame (7.4 x 8.9 cm), in excellent condition, can be installed in place of the store.
