Ebulliometer - 1900s Levesque - Metal - Early 20th centur

Antique ebullioscope, from the Levesque brand, made in France, in the 1920s. The ebullioscope is in reasonable condition, considering that it is about 130 years old; however it is sold only for decorative purposes, as I think some parts are missing (see photos).

The ebullioscope is an ancient scientific instrument used to measure the alcohol content of wine by its boiling point. It was a device widely used in enology (wine analysis) from the late 19th century to the first half of the 20th century and was invented by Louis Levesque, a French chemist and oenologist of the late 19th century.
The ebullioscope became popular in the early 20th century, especially among wine-analysis laboratories and French tax authorities, because it allowed rapid and relatively precise control of the alcohol content in wines and distilled beverages.
