Telescope Revolver 15-20-40x80, Filotecnica Milano Eng. Salmoiraghi, Royal Italian Army, 1917

Triocular Revolver Telescope produced by "La Filotecnica Milano Eng. Salmoiraghi", in 1917, for the Royal Italian Army and used throughout the First World War.

This telescope, completely made of bronze, is equipped with a rotating turret on which three eyepieces of 15, 20 and 40 magnifications are housed respectively and its objective lens is 80 mm.

The turret, together with the barrel of the rectifier prism (removable), is mounted on a sliding element where there is a micrometric rack through which it is possible to adjust the focus with great precision.

The Telescope, thanks to the considerable magnification provided by its lenses, was used during the First World War in observatory outposts and where the Artillery departments of the Royal Italian Army assiduously operated. Thanks to its manufacturing technique and excellent materials and optics used, its use was extended throughout the Second World War: in fact, many period photos testify to its use on fronts such as Africa, Greece etc etc.

There are the original extendable tripod, its rigid canvas container and the wooden case for transporting the telescope.

The vision is clear and sharp and the mechanisms are perfectly efficient.

Excellent state of conservation.

Salmoiraghi was a company resulting from the experience that Angelo Salmoiraghi acquired, after graduating from the Polytechnic of Milan, in Filotecnica, founded in 1865, under the guidance of the founder Ignazio Porro.

In Filotecnica, Eng. Salmoiraghi held positions of manager until acquiring ownership in 1873, transforming the name into "Salmoiraghi, Rizzi e C." for the production of optical and topographical instruments.

In 1877 the company dissolved and Angelo Salmoiraghi continued the business alone with a new company called Filotecnica Salmoiraghi.

At the end of the century he had excellent collaborations: above all that of Francesco Koristka, improving the offer of optical and precision instruments. Under his guidance the company developed considerably, to the point of acquiring a leading role among the producers of optical and precision instruments, the Italian Royal Air Force and the Royal Italian navy.
