Playing a single air, with barillet movement, pinned spring-barrel, stack of eight hooked teeth (complete) with weights on the upper side, winding stem, stop/start pin, suspension loop and weighted base with intaglio crest of a stag with banner and motto "Sinceritas" (honesty), ht. 1 ½ in. (4 cm), attractive patina, movement in overhauled playing condition. - Literature: Luuk Goldhoorn, "A Workable Musical Seal", in: "The Music Box" (MBSGB), Vol. 23, No. 5 (Spring 2008), p. 145. - Goldhoorn argues against use of the term "musical seal" for gold pendants with barillet movements produced during the first two decades of the 19th century, contending that these delicate objects were too fragile to withstand the heat and pressure needed to actually seal a document. The decorative nature of the seal-shaped pendants is born out by their mostly unengraved gold bases, which are too thin for an intaglio. The example offered here is unusual in several respects. Its construction in gilt-metal, rather than gold, lends it an additional weight - at around 50 grams double that of a conventional gold example - and allows for a heavier base with intaglio crest. As Goldhoorn notes, this is indeed a rare example of a "workable musical seal".
