Le Parfait Serrurier ....

Paris: Roret ... Dijon, chez l'Auteur, 1834. Second printing.. Original printed wrappers mounted to paper covered boards.. Good; covers detached; half title and final blank leaf of the binder reinforced along the gutter with a strip of silk backed tape of indeterminate age. The original printed wrappers have been mounted to paper covered binding board. Awkward repair to a tear into one folding plate (no loss).. 8vo, [2], x, [1] - 95, [1 - blank] + 115 plates (2 unnumbered). There is a printed title and engraved title. Author's stamp on the verso of the half-title.

Berthaux's book was reprinted several times. The first was 1828, issued with fewer plates (87) and less text. The second printing is revised and expanded. The sections devoted to lock design and construction, decorative architectural ornaments, and horological wheel-work are the most important. As a handbook there is nothing else like it published in the 19th century.
