Long View 1st Empire

Signed "JECKER | A PARIS", circa 1810, glass, metal, silver, brass body painted black with golden flashes.
Beautiful spyglass or telescope, from the 1st Empire period, with 3 draws. The tips and the three draws are made of brass, plated with silver. The body is painted black decorated with golden flashes. The eyepiece bears the signature of the manufacturer François Antoine Jecker (1765-1834), as well as its hallmark bearing the words "JECKER - Doublé" (with a compass and a square surrounding an Archimedes' head?) inscribed in 1810/1811. Another boot-shaped hallmark (?) indicates silver plating in France. In 1811, the manufacturer Jecker was recognized by the Imperial Institute of France for its work and research. Between 1815 and 1830, he ran the royal factory of optical, mathematical and marine instruments.
