Narcisse Briais letter scale
The catalog of Societé des Lunetiers of 1924 presents this scale under the heading pèse-lettres that is: letter scale. Elsewhere in a catalog of Brewer Frères in 1913 stands next to pèse-lettres also balances pour photographie, translated: scales for photography. And still beneath the picture is added the text ..aussi servir á peser des produits chimiques ou autres objets.. translated: ..can also serve to weigh chemicals or other items.. This little scale was made in France and bears the N.B. logo of Narcisse Briais from Paris. Narcisse Briais was a French instrument maker who crafted letter scales and balances between 1859 and 1886. The N.B. logo was introduced in 1876. After 1886 G. Restorf took over the company and continued to apply the N.B. logo. In 1914 Restorf discontinued the company. After this M. Ducos used the logo N.B. on his letter scales in the period 1915-1926 and from 1927-1931 M. Guérin continued to apply the N.B. logo still on letter scales (source: Le Système métrique 1997-3, page 1124). The design was patented in France by M. Restorf on January 13, 1886 with the patent number 171632. In the ISASC
