The inscription and signature identify either Nicolas Guillemin, matre in 1729, recorded by Tardy on the rue Ste Marguerite in 1740, the carrefour St Benoist about 1744-48, and the rue de Grenelle about 1772-78, or his son Nicolas-Louis Guillemin, matre in 1743, who worked with his father between 1743 and 1748, when the present cartel d'alcove was probably produced, before being recorded on the rue des Boucheries in 1749.
Three identical cartels d'alcve are known, all with cases stamped by Saint-Germain (matre fondeur-cisleur-doreur in 1748); the first, the movement signed Etienne Lenoir (matre in 1717), is illustrated in Tardy, La Pendule franaise, Paris, 1974, Vol. I, p. 188, fig. 1; the second, the movement signed Gosselin (Jean-Philippe matre in 1717 or Jean-Baptiste matre in 1743) in H. Ottomeyer and P. Prschel, Vergoldete Bronzen. Munich, 1986, p. 116, fig. 2.5.7, and the third in P. Kjellberg, Encyclopdie de la pendule franaise, Paris, 1997, p. 95, fig. f; another clock of this model, missing the end of the flowering branch on the left side of the asymmetrical arched cresting is also illustrated by Tardy, Vol. I, p. 187, fig. 1.
