This is one of the very first standard barographs produced by Richard Freres of Paris. With the serial number 267 it would have been manufactured in 1890 - the first year of production. The movement became the basic format for barographs for well over 120 years and is still produced today. Many leading UK manufacturers, including Negretti & Zambra, bought the movement and incorporated into their own display cases.
See extract from Casella's trade catalogue describing Richard Freres instruments dated 1894.
This particular barograph is in 'museum' condition and perfect for a discerning collector.
